Getting really over it

Guys, I’m tired of TTC. It’s been 6 months since my miscarriage. 6 months of trying. Every month I get BFN, every month I get extremely stressed out. This month I completely quit smoking cigarettes, in hopes maybe that’s the reason, just to find out, I DIDNT FREAKING OVULATE. I for the past 6 months, on the 20th day (not CD20, actual calendar 20th) I hit my peak. It does not fail, every month it’s the same, except this freaking month! I didn’t track opk but on the 20th I decided to take a strip to make sure I’m still ovulating like I always do (my breasts didn’t hurt so I was confused) and the test was negative. It’s been 4 days since the 20th and the tests are still negative! So I guess I didn’t ovulate at all this month. That’s just great. And I used my last OV strip today and the urine ran so it didn’t even read correctly and I’m at the point where I don’t even want to get any more tests.. so I guess I’m out this month and probably next month depending on when my period would like to arrive. My periods just got back to regular maybe 4-5 months ago. So this just sucks…
