We had a miscarriage in February had only been trying 2 months. Started again almost right after I was back to normal. This month I decided me and SO would bd every other day no matter what. My hubby has a crazy sex drive so no problem for him lol. Well got my positive opk on the 18th, tested on 9 dpo and 10 dpo got BFNs. I was super bummed cause I just had this feeling that I really was...well I waited 3 days and went and hot first response and sure as shit BFP. Also I use pre seed and SWEAR by it. Took us over a year with our son and the month we used pre seed I fell pregnant with him. Keep on trying ladies. Always try and stay positive that is the best thing you can do...
