Sharp vaginal wall pains, ovary/tube pains, history if endometriosis, what could they be?

For about 2-3 hours last night & the day be for, I felt sharp stabbing pains in my vagina ... on the inside. Felt like pains were in the vaginal walls, cervix as well as up higher where my ovaries & fallopian tubes are located. Not the uterus. The pain up higher was coming from more of the left side ovary/fallopian tube. And, the sharp stabbing/sharp cramps were along the vaginal walls. Also, accompanied with diarrhea the last two days (wasn't intestinal pain, i know the difference).

Medical history:

I have a familial history of endometriosis, but haven't had it confirmed via laparoscopy. However, given no woman on my mother's side of my family has kept her uterus past 36 (except my aunt ... she struggled & held on until she was 40 after having a heart attack due to the birth control they gave her to control the disease).

I'm 34, married, no children, but do want them one day. Took birth control from 15-30 years old until i was struck with debilitating migraines 4 to 5 days a week. I'd go to sleep at night with the migraine & wake up with it just as bad. It was a freaking nightmare that got worse & worse & over the course of one year & several attempts to find a lower estrogen bc, I was instructed to stop taking bc as its side effects outweighed the benefits. However, that left me unprotected to the endometriosis that my ob/gyn assumes i most likely have. Thankfully, i know only get 1-2 migraines per month rightaround the time my estrogen spikes a week before my period.

Periods are extremely heavy, lots of large clots for a few days and last from 7-10 days. My cycle is 21 days (used to closer to 14 ... I'd get my period basically twice a month). Periods are gradually getting heavier over the last 4 years of not using bc and WAY more painful. I spend 1-2 days a month in bed for migraines as well as at least 24 hours of crippling cramps on the first & second day of heavy bleeding. I'm talking fetal position on the bed, lamaze type breathing exercises to get me through the waves of pain, cramping that feels like back labor pains and internally it feels like someone is scrapping out my insides with one if those tools you use to scrape out pumpkins for Halloween. It's unbearable. Even with several vicodin the pain doesn't go away. Heating pads help on the abdomin & back.

Ok, so that's the med history ... what's up with these new sharp pains (not during period)? Anyone have similar med history & experienced this?

Thanks for the advice ;)
