So last Friday i had to go to the ER during the night i was bleeding & when I went to pee it was full of blood and my left side was hurting. They said everything was good & just to go yo bedrest. Well pain & bleeding went away. But for the last two days my lower abdomen been hurting same with my lower back. It got to a point that I could barely walk. Idk it I should over worry and go back to the ER. (Dr is out of the country until the 19th) & what so I do?
