I have pcod and I usually have irregular periods. I had my last period around 29th January and before that around 27th December. I did?t get any period after that. I had oral sex with my boyfriend on 5th march and he rubbed his genitalia on my vagina and used his finger that may or may not have his ejaculation. He was wearing a condom. I took an ipill 3-4 hours after intercourse. I had spotting on 11th march and a heavy bleeding that lasted from 12th to 16th march. Should I take a pregnancy test?
