Aunt Flo is freaking me out

Hi March Mamas! So I’m freaking out a little bit because I’m 4 days late. I’m never late. I’m a Regular Roy when it comes to my period. My doctor warned me that my period might be irregular for a few months after giving birth but 6 weeks later Aunt Flo showed up and has been regular, if a bit heavy, since. That is until now. The kicker is that my husband and I haven’t had sex since BEFORE my last period. It may have even been before my last two periods. We aren’t having issues, just two people who get home and are exhausted by the time baby girl goes to bed. I have no clue what’s going on. I had never missed a period until I got pregnant last year. I’m so confused.
