Ttc 5 months

I’ve been ttc for 5 months and no one told me or prepared me for how sad and lonely this is. My partner is so supportive but it’s just I try so hard and nothing. I ovulate. I confirm it with opks & bbt also had blood test. I lost 20 lbs and exercise daily and changed my diet. Me & my bf take supplements. I just want to be pregnant already I don’t know what is wrong.😔 I’m so nervous I have blocked Fallopian tubes or something.
