Ttc

I’ve been trying to conceive for some time now, me and my partner both want this more than anything, every negative test is eating away at us because all we want is a baby, I have an almost 3 year old from a previous relationship, I was just looking to see if anyone’s had any luck ttc, Any tips or tricks that can help? My cycles and periods are irregular, I have no idea if and when I ovulate as I’m not tracking. I bled from august 12th to august 22nd and had no bleeding since, one of my apps say I’m due on in 4 days but I have no idea how true that may be.
