Thought i was 10 weeks preagnet going by the first day of my first period. Then when i went for an ultrasound found out my baby was 6.2 weeks. They said it could be that I misscarriged then got preagnet again or I had no fetal development after 6.2 weeks. Please if you have ever had this happen let me know. Me and my husband think we lost the baby but the Doc said it could be we just got preagnet again. Confused and going back next week for an ultrasound again looking for a heart beat my hormone levels are those of someone who is 6 weeks wierd.
