My bf fingered me last December 22, im confident that i won't be pregnant since it has no semen when he did that. I got my period last january 1-5 (5days). However, beginning of february, i feel gassy in my stomach and i keep burping and farting. my poop is also mucus-like or watery and i'm having nausea too sometimes after eating (maybe because im full?) so, im wondering if there's a possibility that i'm pregnant?
