I am in my 20's- have always had a week of brown spotting before my periods. I got pregnant while on birth control with my first; we "tried" for my 2nd and got pregnant that 1st try- and then our "3rd" baby was a surprise- another birth control baby; and ended up being babIES! Twins! Fraternal; so my fertility is stellar. Spotting has NOTHING to do with it! Don't worry ladies. Don't trust advice online; this is not accurate information!
Hugs!!
