Go easy on me please. I realise I've been stupid. Had a Mirena fitted a few days ago. On day 7 of my cycle. Was told to abstain for 7 days. I didn't. Had sex on day 2. No additional contraception. Read online that if the mirena is fitted within 7 days of the start of your cycle you're protected immediately. Do you think it would be sensible to take the MAP?
