20+ months & still no period...

Hey y'all just curious if anyone else has had their period stay away this long...

I have 2 boys and both have/are been/being breastfed. I breastfed my 1st son for 15 months and I plan on breastfeeding my 2nd son for about 18 months.

With my first son, I was the breadwinner and my husband stayed home, so I had to pump ALOT. My period came back when my kiddo was about 6months old.

With my 2nd son, my husband is the breadwinner and I mostly stay home so I don't pump that much. My 2nd son is now 10 months old and my period has not came back yet.

Is this normal?

I'm not mad about not having a period but my husband and I want to get pregnant with our 3rd and final child sooner than later so I kinda need my period back.

Any tips, advice, stories, etc...?
