I have a long term relationship and when he comes to visit and we have relations the next day I am always sick.

The intercourse is extreme and afterwords I am exhausted but the next day I get a migrane.

Sometime I started my period weeks early twice, and once I blacked out the next day.
This isn't unusual for me I have had to go to the urgent care once and the hospital another time.

I am trying to figure out how protected sex can make me so ill.

Anyone know?
