Unlikely

Okay so I know it’s “unlikely” for pregnancy to occur after getting your tubes tied. But honestly I’m kind of worried. I’m two days late on my cycle and I’m almost 4 months PP. I’ve had two periods now but my last period I started two days early, could it just be I’m stressing myself out?? Or maybe my body is still trying to regulate the hormones and my cycle? I’m going to buy a test today just in case because I am freaking out a little. It’s probably stupid to feel this way but my husband and I have 4 kids between his previous two, my previous one, and then one together. And we DO NOT want anymore!! Our son isn’t even 4 months old and that’s why I got my tubes tied was to prevent pregnancy.
