Funny you should ask...
I had my m/c and D&C in November and have been trying ever since. Our son was unplanned and we got pregnant quite young, so we had no problems getting pregnant with him, and we got pregnant the 1st month we tried after being on BCP's for 9+ years. So, when we had month after month after month of not getting pregnant, I decided in May to call and make an appt to talk to my doctor.
I figured that it was better to go and just have things checked out rather than keep waiting if there is a reason I am not getting pregnant. I also decided that if I made the appt (which was for 6 weeks out) and then was pregnant, than that was FINE!!
So, we went 2 days ago and now have a plan of action. I will test next week, but if AF shows again, I will feel better knowing that at least I have a plan of how I am going to get my BFP.
I recommend you call and at least set up an appt, but you ultimately have to do whatever you feel comfortable with.
