TTC blues

We already have a 3 year old and we’re trying for #2 and we just can’t! My SO and I always have sex and every month I always think it’s the month I get pregnant. But then my period comes and I just get upset at myself! I get depressed, I blame my body, I just get emotional! We’ve been watching what we eat/drink, we exercise, and I take prenatal vitamins. But every month... period! People always say. Well don’t think about it and it will happen. But I can’t help but just think about it you get it! I just hope I get pregnant soon! Sorry just had to vent a little
