Rant..no negativity please.

I'm so pissed and hate all these girls on here who don't want to get prego or "accidentally" happens to. Like how you accidentally have your SO cum in your vag? (Yes I understand rape is different, shout out and support and love to you select few!) but seriously. 
I've been trying for over two years.. I'm so discouraged and getting very depressed over it. 
I'm not over weight, I'm in my 20s still and my cycles are about 28/29 days apart. I just don't get it. I've use OPKs, track my CM and bbt and have sex then too! AND NOTHING. 
I've seen a doctor, who ran blood tests and did an hsg. Said everything is fine and to keep trying.  Like what?! 😭
Any advice? Help? Anything I can do?! Please. Someone help a sister out. We just want a family. I feel like a failure as a woman.....
