Took clomid days 5-9 of my period and I ovulated 7 days ago. I am having FIERCE intense cramps and back ache like I’m on my period and it’s a really bad one. Heating pad type pain. Had a temp drop yesterday (6dpo) And the nausea is making me not want to eat anything ... if these are all the side effects of clomid then I dunno man 🙁What could be going on ? Does your temp drop 8 days before your period ?
