It is so frustrating ttc

My husband and I have been try to conceive for about 7months. It has become so frustrating because, I have never had this issue. I have 2 girls and he has a son and we want a child together. It has gotten to the point that we have been taking fertilaid for almost 2months and I have been taking ovulation boost and fm pills for about 3weeks now. Since I have been taking this I feel tired, my boobs hurt, I am gaining weight. My period is supposed to start in 2 days but will it hopefully not. This is ridiculous, they say not to stress about it but how can you. It's upsetting and you get emotional too. I also had one beer and got sick off of it.
