I took emergency contraceptive a week and a half ago, then had a 7 day period that ended 2 days ago. i now have some vaginal bleeding, only enough to see on the tissue. it's a rusty color. is this normal? could i be pregnant even with the period?

Emergency contraceptive does alter hormonal balance and could explain the spotting. You are unlikely to be pregnant. Do a home pregnancy 3-4 weeks after the episode in question. Use contraceptive all the time, every time. Get HPV, Flu and Covid vaccines. Wish you good health! Safe sex: https://www.hopkinsmedicine.org/health/wellness-and-prevention/safer-sex-guidelines

Most unlikely. If you are worried do a home pregnancy test Good Luck
