Okay. So I found out I was pregnant Dec 12 with positive pregnancy tests. (the lines were obvious.) My last period was Nov. 16 and I ovulated later around Dec 5th. According to my last period I will be 7 weeks pregnant tomorrow. According to my ovulation I would be about 6 weeks and 1 day. I had an ultrasound when I was (according to my last period) almost 5 weeks and they saw nothing not even a gestational sac. Fast forward to today I had another ultrasound and there was a gestational sac but that was all. no yolk sac, no baby, nothing. My gestational sac was measuring at about 11 mm which is apparently about 5 weeks and a few days measurement. I have been a mess and crying all day because I feel like this is going end in a blighted ovum and result in miscarriage. I have an ultrasound set for next week to see if things have progressed. I feel like I'm living in a nightmare. Has anyone else gone through this? please help me!
