I'm feeling really down

Melissa • 28 married to my childhood sweetheart ttc one more after all the mcs and ectopic pregnancies. fx
Af came on the 6~10. Had symptoms I swore were pregnancy related. Ugh. Hubby has a Low sperm count. We are still trying but not as hard anymore. We are just about done with trying. This will be our last time and if it doesn't happen I'm getting my tubes tied. I'm 28 and don't wanna be 30+ getting pregnant. Any advice on what might help? Baby dust ladies.
