Is it LIKELY that I can be pregnant? I had an oopsy 3 weeks ago, we used the pull out method & although I know now actual cum went inside, I’m worrying about precum. Yesterday I felt a little nauseous & that alone put me in panic mode although it could also be because of my anxiety & because of post nasal drip. I’m only 3 months PP so I still don’t get my cycle back. Today morning i tested & got back a negative, could it be a false negative? If so, by when should I retest? TIA
