Around 5 weeks right now and a first time mom.. my fiancé and I had sex this morning..a little rough by nothing crazy... I started bleeding.. I'm now freaking out.. like bad freaking out. It's pretty much stopped..now jut really really light pink when I wipe..but should I be worried? I have no cramping..I'm so scared...Should I go to the hospital just to be safe? Any advice is welcome
