The chances are too low right?

I gave birth December 13th of last year to baby #2 I’ve been 100% breastfeeding and still no period but I’ve been super crappy for like 2 weeks, emotional, and craving sweets.. is my period coming or could I be pregnant 😳 wouldn’t be upset or anything but it’s not technically impossible that I could be pregnant we were having unprotected sex a lot last month but is it likely idk .. I took a dollar store test but I messed it up, I got another generic test and gonna test tonight I just wanna know if anyone else has similar experience and what the outcome was
