Something worse? Endometriosis symptoms or something else...

First off, I'm new the forums.

I'm almost 25 and was finally diagnosed with Endo last Feb. via laparascopy. I've had painful cycles though since I was 13. I was told in 2002 that I might have endo (but they weren't sure) and they put me on BCPs. I've been on 6 different kinds from 2002-2007. I've been married for over a year now and my husband and I are thinking about conceiving. So, in Oct. 2007, I stopped taking the pill. My periods were ligther and shorter than before.

This brings me to the current issue. About 2 weeks ago, I started having pregnancy symptoms: nausea, higher temp, cramping, extreme sleepiness. Took 5 tests over the last 2 weeks and they're negative. Got my period last Tuesday. It was lighter than usual and over the 4 days I had it, it was constantly stopping and going. So, realistically, I only had it for 3 days or less. Now, I had a pain in my left side by my ovary that feels like a constant light pressure. This week, this pressure goes from ok to bad. It feels like someone steps on my ovary. My concern; tubular pregnancy. Would any of the symptoms I had point to tubular pregnancy at all?

I can't get in to see my Women's Health Care provider or my regular doc for several days to several weeks. Would this be something worth going to the ER for?

Any info or insight is greatly appreciated. :-)
