Never heard of that. We had sex just about every day. We started trying in January and I lost my pregnancy on March and got pregnant again in May This was in 2022
I had sex all the time multiple times a day and we didn’t have to try for long
On nhs its recommended every 3 days when trying as sperm can get tired, we got pregnant the first month trying it this way, the months before we were doing it more frequent and didn't get pregnant x
I think it's too do with better sperm quality or something along those lines
I find that rediculous. Theres always a chance of pregnancy when having sex.
