I'm about a week late, had 3 pregnancy tests come out negative. The last couple of days I've been pretty bloated and having dull back cramps in the middle of my back.

Yes, they are. but it could also just be your period on it's way depending on if you are ever irregular.

If AF doesn't show and hpts are still BFN, maybe a Dr. appnmt is your next step.
Sometimes hpts cant pick up someones HCG at all, but it's very rare.

How long after conception do you begin to feel symptoms of pregnancy? and, if you are feeling symptoms, shouldn't there be enough HCG in your system to register on a pregnancy test? does anyone have any insight?

As soon as you miss a period (if you're regular) then take a test. I'm extremely irregular, so it was more difficult for me to know when to do a test. sometimes I'd miss a period completely.

I'm 9 weeks pregnant and had my last period Dec 26th. I waited til way after Jan 26th to do a test. Infact, 2 weeks after. I did a digital test (sometimes a faint line appears even when you're NOT pregnant on cross indicator kind) and I walked away from the test. It came back as positive. I did another – the same happened. It will ONLY show as positive if there is enough HCG in your urine.

I still have very little symptoms of pregnancy. I get worse symptoms when I would have a period, than what I'm having now. and a Doctor has confirmed I'm pregnant. every woman is different, however most get symptoms from as early as 6 weeks pregnant.

Bad gas is the best way of telling if you're pregnant. If you cannot stop burping and farting day after day – there's a good sign.

I felt "different" during the 4th week. I didn't start feeling the nausea and vomiting, frequent urination until the 7th week. I'm currently 8 weeks. HCG should show up for sure a week after your missed period. If it's still negative by then, most likely you're not pregnant. be careful though, if you're trying to conceive, your mind can play tricks on you around the time when your period is due. very rarely will a pregnancy test not pick up any HCG a week after the missed period. But if you want to be sure, have your dr give you a blood test. good luck to you.

I took a test around 4 weeks and it was negative so I naturally assumed I wasn't pregnant. I got a light period around 41/2 weeks. Than around 51/2 weeks I started getting extreme nausea, very tender breasts, and backaches. Anyways right at that time I took another test and it came back positive. I would think that once you have symptoms thats when you definitely have enough HCG in your system but I could be wrong… in my experience that's how it was

I started feeling sick about 3 days before my period was due. I didn't take a test until I was 4 days late and it came up straight away. just because you're getting symptoms doesn't mean it will show up on a pregnancy test, it's to do with how much HCG is in your body

I think it depends on your body. I started feeling symptoms around week 6. I was mostly really tired and had stomach cramps. I took a test and it was positive.

pituitary either follicular cysts or corpus luteum corpus luteum cyst, an intramuscular injection of 200 international units of cattle and 400 international units, usually 3 days to 6 days after the cyst symptoms disappeared, the formation of corpus luteum, 15 days to 20 days to resume normal estrus. as 1 week after treatment did not see better, to a second drug, the dose is slightly larger than the first.

hCG can promote the formation of corpus luteum function. cattle intravenous 2500 IU or 3000 IU intramuscular injection of 0.5 million to 1 million international units, dissolved in 5 ml of distilled water.

persistent corpus luteum

ovulation (without fertilization), the corpus luteum but not gone beyond the normal time, called persistent corpus luteum. the persistent corpus luteum secretion of progesterone continued to inhibit follicular development, resulting in long-suppressed estrus cow, causing infertility.

cause improper feeding management (feed, simply, lack of vitamins and inorganic salts, lack of exercise, etc.) uterine disease (endometritis, uterine fluid or empyema, incomplete uterine involution postpartum uterine fetal death or within the tumor, etc.) can affect the body back and absorb yellow, and a persistent corpus luteum.

symptoms of cow estrus cycle stopped for a long time without heat, rectal examination may touch the side of the ovary increased slightly harder than the real ovary. if more than the time that should be in heat and not heat, at an interval of 5 days to 7 days, the 2 to 3 times a rectal examination. if the corpus luteum location, size, shape and hardness did not change, then diagnosed with persistent corpus luteum. however, in order to distinguish between corpus luteum of pregnancy, the uterus must be carefully checked.

control should be eliminate the cause, to promote self-luteal regression. Therefore, we must improve the feeding and management according to the specific circumstances, or the first treatment of uterine disease. to make persistent corpus luteum rapidly shrinking, use of prostaglandin (PG) and its synthetic analogue, it is really effective luteal solvent. prostaglandin, usually 2 days after treatment to 3 days of estrus, breeding that is able to become pregnant. prostaglandin W 5 micrograms to 10 mg, intramuscular injection. forefront of enolase can be applied fluoride or cloprostenol 0.5 mg to 1 mg intramuscular injection. injection once, usually in a work week, such as ineffective can be an interval of 7 to 10 days to repeat.
