I'm a breast feeding mom! I also supplement because I have a low supply my husband and I just had a pregnancy scare and our littlest is only 7 months old any moms out there have a recommendation on birth control that didn't effect your milk supply? I used the paragaurd after my twins that are four now and I hated it I got awful cramps from it.
