Sex & Periods

Hannah
About 6 years ago I was diagnosed with PCOS, and since puberty, I have had very irregular periods. It would come with 6 months in between to 6 days in between, to sometimes just not at all. 2 years ago I started dating my now fiancé, and ever since we started having sex, I've had my period regularly. It's the strangest thing, but it's amazing! My hormones feel leveled out, I'm less psycho and my skin cleared up. I think my body is trying to tell me he's the one so don't fuck it up. I'm just curious if anyone else has had this or heard of it?
