I am 5 weeks and I'm also feeling a bit like this. Not been in agony, just felt like i am getting my time of the month and sharp pain if i sneeze/ pulling pain if i stretch.Thanks both, 4/5 weeks so very early. I've spoken to my GP and they're monitoring hcg levels at the moment, just looking for other peoples experiences. It does feel like my period is going to come and any time i cough or sneeze it's sharp pain.
I just assumed that it was all normal though so haven't been worried. Did your doctor seem concerned?
