Opinions?! January 14th I started bleeding lightly. I went to the hospital and they did a urine pregnancy test and it was negative. Therefore they did a blood test to state I was pregnant. At this time, I already knew I was pregnant. The bleeding had me worried so I went to the ER to see what was going on. The doctor said it could be a possible miscarriage. I had an oultrasound done and the baby was okay. The next day I still felt like something was wrong so I had my mom make me another oultrasound visit and the baby was okay. I still had bleeding at this time. That weeekend I was in a lot of pain and cramping. Monday morning I felt something. I went that day back to the OB and they did a beta test and my hormone levels had went down again. That being said the doctor said I had a miscarriage. I went to my two week checkup to do another beta test to make sure my hormone levels were completely down. Well the middle of February everyone else either had their period or were about to get off. So i took a pregnancy and it was negative. I waited till after my "period" was suppose to be over and I took another pregnancy test and it was postive. I have already been to the doctor to say I was pregnant again. Well I have been looking bigger than what I should for just being pregnant again. I have spoken to my mother about it and she thinks I might have not had a miscarriage or I was pregnant with twins and had a miscarriage with one. Keep in mind when I had my suppoably miscarriage I was only 6 weeks and I did not have a DNC. And I did have sex a couple weeks after. What are your opinions? It has had me very scatter brained
