I downloaded tons of <a href="https://play.google.com/store/apps/details?id=com.glow.android">fertility tracker</a> apps last night, this being one of them. My periods are roundabout the same time every month lasting 6/7 days and I started on the 23rd of this month and I'm due to stop the 29/30th according to each app. Yet the ovulation dates on every single app are different. I read online too much sex can just lower your chances of getting pregnant because the sperm isn't mature enough...  Would sex every other day from the day I come off my period do the trick? I really want to be a mum again, my little boy needs a sibling and I don't want too much of a gap between them both :( x
