vaginapagina | Person Unintentionally Inducing Menstruation? (Reply)

Hello lovelies.

I've searched around Google & the like for an answer to this, but I don't exactly know what to search for... anyway! So, over the past few months, my period seems to be induced by a certain person. i.e., whenever I see said person vaguely around the time my period is supposed to show up, BAM. My period is there within an hour.

It's happened three times in the past seven months and I am baffled/intrigued, to say the least.

So this menstruation-inducing person happens to be my girlfriend who I only see in person for a significant period of time once or twice a month. The first time it happened was July--the first time I saw her after we got together. So after about half an hour of spending time with her, I feel my period come and rush to the bathroom. Weird thing? I wasn't due for three days. But I didn't think much of it.

Then I didn't see her much until December, when we went in vacation together. I didn't bring any menstrual products with me because I thought I had another week to go, but I spent an hour with her in the car and suddenly I'm telling my dad to pull over at the next rest stop. By then, was very suspicious.

Fastforward to this morning. I was due about four days ago, but wasn't too surprised that I missed it because the stress of midterms has taken an unspeakable toll on me. But anyway, since I knew I'd be seeing her this morning, I put a pad on just in case, and sure enough within half an hour of her arrival I'm menstruating.

WHY DOES THIS HAPPEN? It wouldn't bother me so much, except that I ended up doubled over in menstrual cramps on the one day a month I get to spend with m'lovely and she was very concerned. I know that stress can delay menstruation, but if that happens, can intense relaxation bring them back? Could she have some intense pheremone action going on? I love her with all my heart, and I'm trying to find some explanation for this. It's just too weird to be a coincidence. Any ideas?
