Late period

Tiffany • i have 5 daughters and 2 son. Getting married just not sure when.

Please help I was to start my period on Dec 27 and now it's Dec 30. I tested on Dec 27 to make sure I was pregnant and it said negative. I just had a baby 11 weeks and 4 days ago. So my body isn't ready to be pregnant again. I wasn't trying to get pregnant right now. And my boyfriend already said he doesn't want any more babies cause we already have 7.
