2 dpo fullness feeling on left side? Clarifying - not asking about pregnancy symptoms.

I’m 2-3 dpo but have a heavy fullness feeling on my left side.

I completed my first round of clomid cd 3-7 and had a super positive opk on Sunday 12/2

I’m not in pain but I have a weird ache and fullness feeling on my left side. I’ve read that some women have had to be hospitalized due to ovaries swelling and not releasing fluid.

Has anyone experienced this? What should I be on the look out for?
