First 18 months, first 16 months just having lots of sex, then used ov sticks for two months and got a BFP. Unfortunatly she was stillborn at 36 weeks, I then fell pg three months later only to suffer mc. We then used ov sticks for the next 9 months and got pg again only to suffer another mc.
Then a full 9 months later we fell pg, we were using ov sticks but not that month as we both had bouts of flu, and only had sex once!
But I will say everytime I fell pg was after a weight loss of more than 10lbs. So weight doesn't help.
Oh and I'm 25 weeks and everything seems fine
