7 month old baby and late for my period...

Tomorrow morning I will be taking a test because I'm 4 days late for my period. Since I got my period back after having my son, I've had them on the 4th of every month. No sign of AF this time around. I'm so incredibly nervous. I knew this was a chance as we were having unprotected sex and I'm not going to be upset in the slightest if I am pregnant again. Im just nervous, naturally. Please no hate comments. I just needed to get it out.

**Update**

Test was negative.
