I didn't know ttc would be this hard 😔

I used opks and I had sex the day before ovulation I didn't temp but I was hoping my period wouldn't come sadly it just did today. I've been trying for 13 months I went to my ob gyn to see if the chlamydia that I had twice before would be a problem she told me no I should be fine. I don't have any thyroids, cysts, etc everything is normal. It sucks cause me and my boyfriend have had sex a lot and it just is a disappointment every time my period shows up I don't know how I can't let it affect me and think positive :/
