Clomid - Ovulation + Nausea ?

Hi ladies!

I believe I’m gearing up for O (not tracking via anything this cycle to remain more “calm” and just BDing every other day). I historically O on CD20/21 so my OB wanted me to try clomid and see if it would help stimulate earlier O. Anyways, I have horrible back aches (my normal ovulation sign) and twinges (more yesterday on my right side) but this cycle I am extremely gassy + have loads of nausea which idk if it’s related to Clomid or Ovulation or a combination, have any of you had this before? I took 50mg cd5-9 and today is cd15.
