I have a history of PCOD I haven’t had sex,

Patient: I have a history of PCOD. I haven’t had sex, but my boyfriend might have gone third base with possibly a drop of semen on his finger. I am a week late now. The home pregnancy test shows negative result. I took Deviry 10 for three days. I feel cramps coming but I’m insanely scared I might be even remotely pregnant. Please let me know. Is it even possible ?

Symptoms: Missed (late) period

Doctor:
