Am I pregnant part 2

My ovulation was on between 20-26 January. And I experienced a couple of days of spotting, including some clotting and shedding of my uterus lining. But I have had this happen every few months, so it’s not uncommon for me to have it.

Anyway my period is supposed to be due on the 7-8 of February, but I’m experiencing some cramping-but no period as of yet. I have had it come early but it’s rare. The past few months has been on the same time each month.

I did have sex on the 15 and 16 of January with using a Condom.

I can’t sleep as my anxiety is through the roof

So I don’t know if this will help but I’ve been on sertaline for almost a month.

Plz help.
