"Taking your partner's cycle"

DiShay
Idk if it's "taking your partner's cycle or not, but I just had a period and it ended in June 1st and I started ANOTHER ONE June 19th. 🤦🏼‍♀️ She experience pre menstual symptoms and so did I. She also didn't  come on but I did.  Is it a possibility that I came on her cycle for her or is some type of sync?
