I'm sure I'm worrying about nothing but I just need some reassurance! Im 4 weeks pregnant (1st pregnancy) and for the last few days I've been having stomach cramps on and off throughout the day - they're mild but quite consistent. It feels exactly like my period is about to start (although not quite as painful), and I cant quite shake the feeling that it is going to! I have mild anxiety every time I go the toilet thinking that I'm going to see blood. HCG levels seem to be rising very well with darker test lines every day. I'm guessing this is all normal?
