TTC with pcos!

My boyfriend and I have been TTC for almost a year! It's been a long journey. These past 4 days we have been BDing feels like nonstop. I don't think I was ovulating because it's hard to know when. And I understand it's to soon to have symptoms. Or anything. But today I started have a little bit of cramping and now my boobs are kinda sore. So I don't know what to think.
