Where is my period!!

My DD is now 6months old.

I only breastfed for 4months, and have yet to have my period...


I also had my tubes tied when she was born... ..


........ but I googled and read that you can actually still get pregnant with tied tubes, so now I'm like WTF...  

My mom got hers tied and didn't have one for a while. I think they might've even put her back on BC to help it. (not a hundred percent sure) But now I know she has one every month.
