Swollen/Tender Breasts:

Swollen or tender breasts is a pregnancy symptom which may begin as early as 1-2 weeks after conception. Women may notice changes in their breasts; they may be tender to the touch, sore, or swollen.

Other Explanations: Hormonal imbalance, birth control pills, impending menstruation (PMS) can also cause your breasts to be swollen or tender.

Fatigue/Tiredness:

Feeling fatigued or more tired is a pregnancy symptom which can also start as early as the first week after conception.

Other Explanations: Stress, exhaustion, depression, common cold or flu, or other illnesses can also leave you feeling tired or fatigued.

Nausea/Morning Sickness:

this well known pregnancy symptom will often show up between 2-8 weeks after conception. Some women are fortunate to not deal with morning sickness at all, while others will feel nauseous throughout most of their pregnancy.

Other Explanations: Food poisoning, stress, change in hormonal birth control method or other stomach disorders can also cause you to feel queasy.

Backaches:

lower backaches may be a symptom that occurs early in pregnancy; however, it is common to experience a dull backache throughout pregnancy.

Other Explanations: Impending menstruation, stress, other back problems, and physical or mental strains.

Headaches:

the sudden rise of hormones in your body can cause you to have headaches early in pregnancy.

Other Explanations: Dehydration, caffeine withdrawal, impending menstruation, eye strain, or other ailments can be the source of frequent or chronic headaches.

Frequent Urination:

Around 6-8 weeks after conception, you may find yourself making a few extra trips to the bathroom.

Other Explanations: Urinary tract infection, diabetes, increasing liquid intake, or taking excessive diuretics.

Darkening of Areolas:

If you are pregnant, the skin around your nipples may get darker.

Other Explanations: Hormonal imbalance unrelated to pregnancy or may be a leftover effect from a previous pregnancy.

Food Cravings or Food Aversions:

While you may not have a strong desire to eat pickles and ice cream, many women will feel cravings for certain foods when they are pregnant. this can last throughout your entire pregnancy. Some women develop adversions to certain types of food early in pregnancy and this too can last for the next 9 months.

I started getting symptoms around 6 weeks. I noticed that I was using the bathroom very often, I was becoming extremely tired, I actually lost weight because I was experiencing a lot of nausea. you can start experiencing symptoms as early at 4 weeks. it is different for all women.

Good luck, and possibly congrats? :]
