Re: AF post partum
With DS1, I took a mini-pill for birth control starting around 6months, and got my period at the end of that cycle of pills. DS1 had supplements with formula 2x a day.
With DS2, I EBF'ed and didn't use any hormonal birth control. My period came back around 18 months, I think.
With DS3, I EBF'ed, and didn't use any hormonal birth control. My period came back around 16 months, I think.
After DS2, it was very irregular for a while. My first cycle was like 60 days, second was 45, third was 35, fourth was when I got pregnant.
After DS3, It took about 5 cycles to regulate.
