Ladies! I just had baby number 3 and we tried the pill and the IUD, after being on the IUD I have had pelvic pain and can actually feel it so hubby and I decided to us NFP (natural family planning) to get to know my cycle so he can finish in me without worry of pregnancy! we went out and bought a BBT thermometer and I downloaded this app to track it! for a few months he is NOT allowed to finish in me until we get a hang of this natural method! any tips or advice for us?? we are excited because in 3 years we want to ttc for our fourth little!
