Looking for some advice, myself and DH have a 5 month old and have not long ago started to have sex again after a traumatic birth. However the condom split a few days ago and I don't think it was near the time of me ovulating but I haven't really been tracking so can't be sure. We've now decided I will go on the pill. With a v small chance of being pregnant again do I start the pill straight away or after my period has started?
