TTC after 12 years

Hi everyone,

I have a 12 yr old son and have pretty much made it my mission to not get pregnant until recently when my husband and I decided we want to have a baby. We have only been trying for a month or 2. The last two months have been different where I get this terrible bout of nausea and lightheadedness with mild pelvic discomfort so much that it keeps me up all night in some distress. This happened the last two months exactly a day or so after my predicted ovulation day. I saw my OB and he says I don’t have any cysts or fibroids and doesn’t feel I have anything wrong with me. Have you ever heard or something like this? Logically, I feel like I’m having some issues ovulating... does that make sense ? Also no positive pregnancy tests just yet! I’m worried I may not be able to!

Thanks for your support !
