2 weeks of sex

I watched a YouTube video saying your best bet if you have a normal cycle or one that’s only off by a few days now and the then after your period have sex for 2 weeks every single day and it’s your best outcome. I like this thought over taking ovulation tests. Thoughts?

The couple doing it were married a pediatrician and she was an OBGYN, she also said that it isn’t true that a man ejaculating everyday lowered his sperm count BUT if he goes 5 days or longer without ejaculation it can lower it.
