Advice! Trying to get pregnant

So me & my bf have been trying to have a baby for about 4/5 months. We don’t use any protection, I have never been on any birth control either. I wanted to know is there anything I could do to increase my chances of getting pregnant.

Side note: when we have sex I get really wet would that affect the sperm from going in?

Also I heard that I should get on the pill for a couple months then get off to help increase my chance to get pregnant. Is that true? Does that work?
