Cramping

I haven’t had my period in a year and was talking to my gynecologist about possible actions to start trying for a baby. We had planned to work on hormone treatments, but with the start of a new year I found out I was pregnant. 2 weeks ago I got a very faint pregnancy test and yesterday I saw my OBGYN to confirm it but he didn’t see anything on the ultrasound. I know it might be a little soon, but I’m terrified. I have a history of endometriosis and chlamydia. I don’t know why they didn’t see even a tiny dot somewhere and on top of that, what feels like my left ovary, is in a good amount of pain. I showed my concern to them and all I got was, “this can be normal.”

That wasn’t convincing. Has anyone had left side pain like a bad period? Is this really normal? I do know the risks and upon bad judgment I read into ectopic pregnancy. I’m just so scared. Also, I have kept an eye out for blood but not even a drop so I’m holding onto that. I have another ultra sound at what they think might be 8weeks so I’m assuming they thing I’m 4-5 weeks or somewhere around that. Anything will help, please.
