Could I be pregnant if I missed my pill last Saturday took it last Sunday but had sex last Sunday as well and missed it yesterday. I was spotting for two days now today I am bleeding light pink blood."

  
 

Yes you could, even if you used the contraceptive correctly.

Most likely not, but pregnancy will always be a possibility, however you wouldn't know it yet if you were. If you find that you have trouble keeping on a schedule for birth control pills, you could try setting a phone alarm as a reminder, or consider an alternative birth control method.

As an added precaution, you could take emergency contraception today and still have some effectiveness as lower the risk.

ANY time there is penile insertion there is the risk of pregnancy. You can reduce the risks, but not eliminate them.
