Hi ladies, 
I had my first miscarriage at the beginning of May and I was very early (about 5 weeks) my doctor said if I had not taken a test I probably would have thought it was my period. I healed well from it and was given the okay for us to start trying.  Well we've been busy but now it's that dreaded wait time. Should I just wait until I'm exactly 5 days before AF should come? I'm just anxious is all.
