ER visit

Well ladies- we were at a baseball game last night and I went to the bathroom before I left and bright red blood was all I saw in the toilet. Went to ER as I was certain I was going to lose the baby.  Baby was ok but have a hematoma.  I have been having pain/ pressure in my lower abdomen for a day or so but figured it was normal growing pains.  So I have to follow up w my Dr on Monday.  I had a small hematoma with my son early on but it resolved and never had bleeding. Needless to say I am worried.
