I'd say if you are worried, check with your GP and if they give the all clear and you are in the mood... go for it! Your little bubba is very well protected in there.

I took 3 years to conceive my first as well with multiple miscarriages along the way, not one of those miscarriages was attributed to DTD - all chromosome problems (yes, I had testing and found out). Pregnancy hormones tend to send me into a sex crazed maniac and I did ask both my GP and midwife if it was possible to overdo it so to speak, they both said that unless I was spotting, it was fine. That being said, it is quite common for some women to spot a little after DTD as the cervix is quite sensitive with the extra blood flowing around your system, so don't panic if it happens...

I'm 18 weeks now and my poor DH is begging for a break!!!
