Pray, pray, pray and when you are done, pray some more!!!!
I can’t imagine how hard that must be! What a blessing that you found your way back to the faith! Maybe your re-conversion will be enough to spark some interest in your husband!
As for info on the pill, if he won’t take it from you then just get facts and have him read it. Here is one link http://www.pfli.org/faq_oc.html. Not only can it cause an abortion, it can do major damage to you for taking it! Blood clots, strokes, and breast cancer just to name a few!
Best of luck & know our family is praying for you and yours!
