For the last 2 days I've been experiencing period-like feelings (queasiness, tenderness and pain in the abdomen) but without the period. I don't keep track of my periods, but they generally happen at the start of the month, though sometimes at the very end of the month before- so I wasn't expecting a period for about another 5ish days.
I never get period pain more than a couple of hours before my period starts, so I kept expecting it to kick in on the first day- but there's been 0 blood.
My periods are at the extreme end of the pain scale.
Also my doctor believes I might have endometriosis, due to a life time of unmanageable period pain (which causes fainting and vomiting frequently), and 2 years of frequent unprotected sex with my fiance which has not resulted in pregnancy. I was referred to a specialist for this, and have agreed to surgery to check my fertility and look for endometriosis.
