Hope I understand: Your question is a tad unclear but I understand that you are worried about pregnancy because you had unprotected sex 3 weeks ago and your GF missed her period on September 23rd. That is easy. Yes, she can be pregnant! Get a urine pregnancy test. Tell her to take iron supplements or eat more foods high in iron if she is anemic. If she can, she should see a doctor.
