TTC for over a year..

Hi, I'm just looking for some tips for TTC. I've tried everything. it's been over a year and I'm still not pregnant. I'm currently seeing doctors. I ovulate normally and I'm awaiting more blood tests. we've tried everything. pillow under my butt. orgasm after sex too(Tmi sorry!!) I'm just feeling so disheartened. I feel like it's never going to happen.
