So I just got back from having a scan and bloods, my hcg was 178 and the sonogram showed a gestational sac measuring around 10mm, womb lining is thick. They want to repeat bloods tomorrow ( had bloods done last night and scan done today but waited to post about both ) I’ve taken 3 tests today and all had a really dark positive ( darker than 2 days ago ) I’m just upset and worrying because she couldn’t see anything to confirm a viable pregnancy. Has anyone else had anything similar and turned out to be ok?
