So for the last 3 weeks ive been feeling weird. i stopped my birth control in aug. and havent had a period since. Ive felt nausea most days can only eat like one meal a day. I get heartburn really bad and got a lot of bloating. I have all the common symptoms of being pregnant but the sore boobs. I took pregnancy test in 2 days 4 came out positive, i went to the doctors and the blood test came back negative and the doctor said there was no sign of pregnancy. My lower back has recently started hurting ..... I have no idea whats going on. Would you think i was pregnant? i took another test this morning it was negative, so im not sure what to do. I dont know whats going on.....this is just crazy to me. Ive never been pregnant before so i dont know.
