Hi. I'm 6weeks+4 and am having cramping. This started about 3 hours ago and has been coming in waves. I'm not bleeding but I'm scared this could be a miscarriage. The pains aren't terrible but are fairly strong. I have 2dcs and don't recall anything like this. I don't know what to do? I'm a police officer and at work at the moment till late tonight. Feeling really scared. Any advice?
