Hi welcome to H.C.M.Forum. this time you are having brownish discharge with cramps in abdomen suggest
presence of infection. which may become obstacle for conception. after continuous use of pills some gap for conception is usual. i advise both of you to consult a gynaecologist, or infertility
clinic for diagnosis of the cause, & treatment of infection. besides i advise you to follow some general precautions. follow male up position in sex. dont get up or wash immediately after sex. have sex between 11th to 20th day of the cycle.
wishing for beautiful baby soon.
