I would like to know if i am able to get pregnant this week.my period started oct 7th lasted six days.i had unprotected sex with boyfriend on 12th?

Best chance 10/15-22: I would guesstimate (if you have a regular 28-30 day cycle) that your best chance to conceive would be with unprotected vaginal intercourse between 15-22 of this month. To be more precise, you can check daily ovulation prediction kit and increase the frequency of intercourse around that time. Take Folic Acid 1-5 mg daily and good luck!
