Dear Doctor , I am 6.3 weeks pregnant.My last period was on 26th December,2015.I have been experiencing cramps in my lower abdomen,which my Gynae said was normal.But during my 6th week I had brown discharge after which I was given 3 times a day Duphaston and Gynaec CVP.Is this normal?Are there any chances of miscarriage?This is my 2nd pregnancy.I have a son by c-section,who is four years old.Please help me.Cramps have reduced ,but still rise in between.I feel my stitch of 1st pregnancy is stretching.
