Postpartum period

Da

My son will be 1 year old on the 30th, we're still breastfeeding, and I've been on the mini pill since shortly after he was born. I had my first period about 2 weeks ago and it was a bit heavier and I had more cramps than normal. I know that can be expected but I started again this morning. The last one had stopped completely a week or so ok. Anyone else experience this or hear of this?
