Pains please help

OK so I'm wondering if I'm forming a cyst or something... I'm on cd 21 and ovulation happened for sure on cd 17. Starting yesterday I had random stings and my lower tummy was sensitive when my husband but pressure on me while BD. Today I'm still having the random stings but it is more of a cramp that last about 3 seconds and I thought I was ovulating again because my tummy just has that feeling and my breasts are puffy but that happens to me during ovulation and the week before my AF but I'm not due til the 5th. I'm not ovulating though I took a test and my cp and cm all say no. What could be happening? Would a cyst make me feel this way? Or am I just looking too deep into things? Tell me straight you won't hurt my feelings thanks in advance ladies! Oh I took 150mg of clomid of cd 5-9
