The Sponge is a polyurethane foam that contains three special spermicides. It releases a spermicidal gel, that creates a barrier, protecting against any sperm passing through to the cervix. The spermicide successfully immobilizes and kills the sperm on contact. If used properly, it has a success rate of 90%.
Dear Lactation Consultant,
I am nursing a 5-month-old baby and recently started taking the nursing birth control pill. After two days of taking it, I started to bleed and continued for three days. It was like having a period. Why would starting a pill make me bleed or am I pregnant? Please advise.
