Hello I had endo laser treatment 2 years ago then had a baby. I had merina coil fitted 6 months ago. But lately have put on alot of weight. (Even though i hardly eat) and lower dull pain in stomach and back. Also "uncomfotable" sex... My periods are really light now but lately have had on/off stabbing pains in groin/cervix area and now i have not got my period just brown rubbery discharge!!! What could this be?
