PREESEED & BABY DANCING☄

So, I've been ttc since I got with my bf in March of 2017. We have never had protected sex because he really wants a child, well we both do but every month I would take atleast 2 pregnancy tests and we never had any luck. This month I decided to try Preseed during my fertile week because I've read so many great reviews on the product and I want to surprise him with this gift of life for our anniversary in March! Everyone around us are having children and we both have been waiting so patiently! We are definitely ready! My fertile week started on Thursday February 8th, and it ends on Tuesday the 13th. Im going to continue to use it everyday to see if I can get a positive test. Until then, I have two questions for you ladies. If you have used preseed before how did you like it? and how quick did it work? My second question is when Should I test?
