Taking clomid - INTENSE cramps for a few hours 7 DPO?

I know that clomid does weird stuff but has anyone ever had really strong cramps about a week after ovulating?  I had them for a few hours Wednesday afternoon which was 6-7 DPO (got the solid smiley both days, bd on the day before smileys and day of second smiley).  Today I've got them at the EXACT same time.  They are evenly spread side to side and really painful. I'm worried bc I do have one ovarian cyst and maybe its OHSS??  Or just weird PMS bc of the clomid?
