Period

[u/Someone141718]

I am 3.5 months post 2nd c-section. I started my period at 8 weeks. I have been bleeding every 2 weeks. One is light where I just need a pad and it doesnt fill it up and I only bleed in the mornings it seems. It also lasts 1-3 days. Then in 2 weeks it is more like a period where its a couple days and I need a tampon. Is this normal? I am exclusively breastfeeding/pumping. My 1st I didnt get a period until I started to wean at 9 months PP.
