birth control and fertility


I've been ttc for awhile now and was talking to cousin who claims that birth control made her get pregnant. I shared with her that I'm ttc and she told me her story . She was ttc for 3yrs and a older lady told her if she wanted to get pregnant.. jus het on birth control for 3 months and stop. she did it and as soon as she stopped birth control she got pregnant. What do y'all think?? and would u suggest someone trying birth control to concieve????
