HELP! Ladies that have taken clomid!

I currently just took my second round of clomid at 100mg and my progesterone on day 21 went from a 9 to a 15

So I’m 8DPO and for the past 2days I’ve had mild cramping, lower back pain, my breast feel “heavier” then usual, I’m completely exhausted!

Have any of you ladies had these symptoms? I read online it can “mimic” pregnancy symptoms?!
