I had my cycle on 9/19-24. had intercourse on 10/1. on 10/3, i had a small amount of blood . could i be pregnant? also i was diagnosed with pcos.

Not too likely: But possible. Ovulation is infrequent in pcos. Wait a little before running a urine test.

Pregnant? : Pcos reduces fertility but does not preclude it, just makes it harder and less likely. Atypically 2 weeks post period is when an egg drops and your timing fits that. Spotting at that time does not suggest u have conceived. U could be pregnant. I would suggest simply test your urine with a home pregnancy test. Make sure to follow the instructions and buy an early detection one.

Too early: Need to wait and see. May need pregnancy test in couple weeks.

Pregnant?: Get a home pregnancy test kit and use it as directed. These are quite accurate. If negative wait 7-14 days and test again.
