So I took my nuva ring out on the 10, and I am supposed to replace it Sunday and I still have no sign of a period. I recently read that if you weigh more than 175 lbs your chance of getting pregnant severely increases.. And lets just say I'm not a little girl. Idk what to think I took a pregnancy test but I'm afraid its too early to show and I might miscarry if I put another nuva ring in if I am so.show pregnant. I really don't know what to do right now.
