Help, BD advice !

E.J.F.

So it’s my fertile window and of course I get a nasty cold. Usually during this time I try to bd every other day but I’m just feeling too crummy.

My opk test isn’t quite positive- normally I’d bd today and tomorrow but honestly I’m not up for it. I don’t want to miss out completely this month though!

Is it enough to just do once when I get a very positive test?
