Delayed Period & Breast Sensitivity After Intercourse: Possible Causes & What to Watch For

Question
On V-Day me and my gf had sex 7 times, four of those times, I ejaculated three times with condoms. But, that last time I pulled out. 6-8 days later her period came as regular. However, since then she's been very tired and a week after her breasts started feeling sensitive. She said she had been tired before then, which is normal cause we have to wake up early for school and she LOVES talking until 12-1 AM. But this month (March) her period came four days late. Today's the second day and she said it was light, but yesterday, it was like a normal period. I'm worried about this. Could she be pregnant even though we haven't had sex since V-Day and she had her period a week after?

Answer
She is definitely not pregnant as she has had two periods. Her tiredness and other symptoms are due to some thing else. May be she should see a doctor about her complaints, but she is definitely not pregnant.
