TMI Please help me don’t judge I’m new here

Jesenia

So as of today it’s been 10 days since I last had sex unprotected . My cycle is irregular due to pcos my last period was April 30th and I haven’t bled since then until today and it was only when I wiped I’ve been crampy as well . Is this the start of IB or a period ? It had a lot of stringy ew mucus as well . This would be baby #3 if it is IB . What do you think ?? Thanks in Advance
