I'm 5 weeks pg and everything was fine until about 4 hours ago. I had really bad period pains. Went for a lie down, got up for a wee and noticed some blood. It's not in my knickers. (sorry for tmi) but when I wee it's pink and I wipe and there's red blood on the tissue. The period like cramps are dying down but I'm terrified this is a miscarriage. Is it normal? Can I do anything to stop it?
