I had ds 8 months ago and still have not had a period. With dd I was back to normal after about 6 weeks so it's a big difference. I bf them both but with dd I expressed a lot, whereas with ds I never do so that might be why I suppose. ds is still on anything upwards of 3-4 breastfeeds (more if he is poorly) a day. When should I start to worry? Or shouldn't I worry at all?! I have had 2 reminders for a smear test but have recieved conflicting advice about whether I should wait until my periods return.
