PAINFUL CRAMPS

Here's some background info, I've recently lost 50 pounds. I did it to improve my health obviously and I've always been afraid of developing PCOS or anything else that would make conceiving in the future difficult. My periods have always been pretty regular and only late a handful times. I've never had a problem with painful cramps during my period but this time I'm not even on my period, it's not due until another 9 days. I started experiencing the cramping yesterday to the point I was in tears so my boyfriend gave me some ibuprofen and I eventually fell asleep. I woke up a little bit ago and I'm not experiencing the same pain anymore but it's a very sore dull aching pain, as if I'm badly bruised.

I do have unprotected sex frequently but I don't see how this could be related to pregnancy? Me and my boyfriend are both a little worried because I've never experienced such intense cramps before and if it doesnr get snt better I am planning on seeing a doctor. Any advice would be great.

My last period was the 13th.
