Hi everyone! I found out I was pregnant on Dec 6th, a couple days before AF due to being extremely tired and having weird dreams. The line came up right away and my husband and I were so excited! A couple days later I was having some concerning cramping so I went to the ER. The hospital was surprised I already knew I was pregnant, due to the start of my LMP being on November 11th, that would have made me super early. The doctor said he would take my hcg levels, and if high enough they would do an u/s to rule out ectopic pregnancy, but because I was so early on he didnt expect my levels to be high enough. 45 mins later they come back and say my levels were high enough to try an u/s. I dont believe they were able to see anything through a regular u/s so they did a vaginal u/s and located the gestational sac. The sac measured almost a week ahead of what I should of been. Fast forward to Wednesday and I have almost unbearable sharp pain, they did another ultrasound and found that I have a complex cyst on my right ovary, and they also measured the sac again which measured to slightly over 5 weeks, and my hcg levels were 5600. Based on my LMP on Wednesday I should have only been 4 weeks & 2 days. My main questions are, if the gestational sac and my hcg range are measuring a week ahead, how is that possible? I know my last LMP was Nov 11 because I mark it every month and it was a heavy 5 day cycle. Secondly, has anyone had a complex cyst while they were pregnant?
