This last month was my very first month trying clomid. I did 50mg. I did not get a positive opk but I did stop testing around cd23 because it's pretty rare to ovulate past then on clomid anyway. Today I'm on cd28. I never start my period on my own. Ever. I never really PMS, and I have to induce with Provera. My boobs have hurt so badly for three days, I can't even touch my nipples because they hurt so bad. The little "bumps" only areola that are usually a very light pink are bright red. My lower back has been aching for days, and I've had crazy vivid dreams like I've never had before for three days straight and have been crying left and right. I've heard of people getting clomid symptoms after ovulating...but I didn't think I even ovulated. I know no one can tell me if I'm pregnant. But is there any chance of this? Is there a chance I ovulated THAT late? Or is there a chance I actually did ovulate, didn't catch it and have a possibility of being pregnant? I've never felt this way before and it's been over 20 days since my last dose of clomid.
