My husband and i just got married in feb. and i had my mirena removed in may we have a 5 year old son but now we are having trouble TTC not sure why i have tried OPK but no luck there and every pregnacy test has been negative i guess my question is what is the average time of conception after IUD my doctor said right after i was wondering if there was something wrong with me because we have been trying but no luck has this happened to anyone if so are you or have you already been pregnant?
