Preseed..

Has anyone used this after 4 months being off BC?!? I was on the depo for 3 months.. it’s been 4 months since i’ve been off of it.. I wanted to try preseed to see if it maybe worked.. It didn’t :/ Maybe luck next month?!? I’m worried its my SO who isn’t fertile. Either way LMK if anyone has become pregnant with preseed after using BC thanks ladies ☺️
