Had a baby by C-section almost 4 months ago and am back on the pill. Ive noticed that just after ive had my period and particularly after sex, my bits smell. This is my 1st baby - is this normal?? Is it ever normal to be fishy?? Its only for a about a wk!! No obvious signs of thrush or anything? Or jumping madly to conclusions has my dp been messing about & given me an std!!
