Periods late 😳🤦‍♀️

Jessee

Soooo my periods late by 4 days as of today…..great. I’m 5 months pp so if I end up being pregnant I’m a little nervous, but it is what it is. I do feel a bit of cramps so it could just be irregular. I’ve taken a test like a few weeks ago, but it came out negative. Should I take a test again? Or maybe could it be because I’m breastfeeding? But then that’s soooo confusing cause I had my period last month. I don’t know, this shits confusing 😂
