5 week PP

So I am 5 weeks post partum, me and the hubby had sex at 2 weeks PP and yesterday I felt off like craving a bunch of things and emotional so I took a test and it came out very faint, I took another and it showed another faint. My question is could this be left over hormones from my last pregnant or could I be pregnant. I am taking another test in 2 days because then I will no for sure but I just wanted some thoughts.

EDIT!

I didn't ask you ladies if it was dumb choice lol I have already been cleared and no infection so thank you for your opinions that was not even asked for ?? Lol it's my body so if I feel like I want to have sex with my husband than I will. Lmao anyways....
