So confused!! Help!

My periods have always been regular. I was supposed to ovulate on Feb 16th and AF on 3/5 but neither happened according to opks and bbt. My bbt was like the rocky mountains too which isn't normal for me. I took a preg test and opk on 3/8 just cause I didn't know what was going on and I had a + opk.. So we bd just in case.. But I've had cramping since 3/3 on my right side.. And I have sore boobs as well. What is going onnnnn?! Could this be from ovulating late? Or is there a chance I'm actually pregnant? I'm so confused. This has been like a 4ww at this point and it sucks. Any insight would be appreciated. I'll take another preg test and opk when I get home today just to see where I'm at..
