Could I be pregnant?


I had unprotected sex last Saturday but he pulled out and I was using spermicide folds. I took plan b probably 5 hrs after that but I noticed one of my apps said I was on my second fertile day but not the peak. Glow said I wasn’t yet. I started a detox that has made my stomach hurt really bad but I’ve felt nauseous at night and have a bad shortness of breath. This is only at night and for a few hours. I might start the pill tomorrow or Saturday as well and my period is due in 2 weeks. Could the nausea be because of pregnancy or maybe it’s the detox?
