Ok I'm 7 weeks after TTC for years and you won't believe the only thing I changed. I quit caffiene completely. Only drank sprite, gengerale, root beer, or water or juice. I was litterally pregnant after the first cycle without caffiene. If you habe ever had large ovarian cysts this could be why. Try quitting caffiene you wont get a cyst and boom pregnant. Might not work for everyone but its simple and free so it's worth a try <3 <3 <3 Good luck and baby dust
