i really think im pregnant but im still taking my birth control pill seasonique. so im not sure when im due for my period. symptoms im having are tiredness, headaches, sharp lower back pain, sharp pains in my cervix and chest, itchy, heavy feeling breats and tender nipples, itchy stomach, achey legs, i pee about every 2-3 hours which is a lot for me. i feel sick constanly and eat a lot lately. i have alot of gas which isnt normal for me. ive ben having a runny nose and im extremely moody. ive noticed a bit more discharge and have been craving popcorn and icecream. what do you think my chances are of being pregnant? also if im still taking my birth control, can that make the pregnancy test say negative every time even if its positive?
