Can anyone offer advice. After having dd1 2 1/2 yrs ago my periods were great, better than before. No pain, not heavy and only 5 days ish. After dd2 11 mths ago periods have been regular but painful and I seem to have 1 week off a month if lucky with no pain then rest of time in pain. Also after having sex got pain around my bellybutton area, is this normal? May have nothing to do with it. Also how often is ok for sex? My mum keeps telling me sex is so important which makes me feel bad as my dh and I are so busy most nights it's tea, bath and bed. Sex hasn't really come into it until recently. Are we abnormal?
