me and my husband decided we wanted to try for another baby, so after having mirena coil in after a year i took it out, we have been trying to get pregnant since with no look, I m slightly worried because I m usually very fertile after having 3 children previously...so when my period didn t come this month i was excited..iam now 4days late and my husband and i had sex 2 nights ago and i had some pink/red spotting during, i thought my period had arrived, so i washed and used a tampon , when i woke up i took the old tampon out and it was almost dry and i have not had any extra bleeding and I m having my normal white discharge and i have did 4 pregnancy test which also come back negative...iam starting to get worried..iam infertile do i have an infection??
