So I got the results from my ultrasound today. Everything looks normal (uterus, lining, etc) except I have 1 large cyst on my left ovary - 10 cm long (4 inches! That's 3 times the size of an ovary).
He said that's likely what's causing all the pain I've been in the last few weeks. He's sending me back to get another ultrasound in 3 months to see if it goes away on its own. If it is still there they will have to do surgery (thru belly button) to get rid of it, unless I'm pregnant by then and then they'd have to do it after baby was born if it was still there at that point. If I'm still not pregnant by then he said he'd put me on Clomid after the surgery - the cyst could be interfering with me ovulating. But he did say that there are absolutely no indicatiors that I have PCOS because it's just the one cyst. So now it's a wait and see I guess! He gave me a prescription to help with the cramps, and hopefully it'll go away on its own.
Thanks for all the positive thoughts and prayers girls! They really helped!
