I know you're not supposed to have sex the night before a smear test as the semen is still in there and will muck up the sample. So, should I abstain the night before a sweep? Purely for etiquette reasons 
I'm going for a sweep tomorrow but have been quite crampy so was keen to try a direct hit of prostaglandin later if I can be bothered, DH is definitely keen. I'm thinking of embarrassing residue on the obstetrician's glove. WWYD?
