TTC rainbow baby

I had a miscarriage in June 2015 and got on BC after. I got off the BC in Late October and started TTC in December. My SO is always putting his hands around my belly and when I ask him why he says "because my baby is probably in there this time" ☹ I've gotten to the point where I just stare at him with sadness. I think it breaks his heart each time AF comes. I know it's only been 3 months of trying but I'm getting discouraged. Have any of you ladies had trouble TTC after miscarriage? How long after MC did you conceive? AF due March 3rd.... Fingers crossed.
