Ok first off I think I might be pregnant (took a test already came up negative period due on the 17th) any how I was bd with my so and I got a really sharp pain on my right lower abdomen going down into my pelvis. We stopped and went to bed. The next morning I was a little sore but I expected that. The pain has been progressively getting worse and is now to the point I can't get comfortable to sleep. Also I started bleeding rather heavily and it's only getting heavier as in heavier than my period but with no clots what so ever. Bleeding started around 10 pm and it's now six am. I'm going to the er when my so wakes up but do any of you lovely lady's have any surggestions?
