5th day post ovulation

Haifa

Hi there , I have PCO and I’ve been trying for more than 4 years this month I took letrzol and had sex 3 times during the ovulations days , now I am in 5th day and I’ve been feeling cramps from second day of ovulation is it a chance that it’s early pregnancy?

It lights cramps with tightness in the right’s side or it just the medication effects? #TTC
