I am just having first af after 2 years due to preg and breastfeeding my lil one. I night weaned her which brought af back. We have been trying for 3 months but cos I had no af I dont think I was O'ing. Anyway now

is back I am gearing up for BD a lot cos I dont really know when I will O. Sooo my question is should we do it every day or every other? I read if you do it everyday then this can weaken the sperm. But cos I dont know when im O'ing I dont want to miss it IYSWIM? Would appreciate some advice xxx
