I would say that if your period that started on Monday, (2 days after unprotected sex) was your normal expected cycle date, then you most likely are not pregnant. When were you due to begin your period this month? If it is within Monday’s date, give or take a day or two, you may not be pregnant. However, I will tell you that anytime you have unprotected sex you can become pregant. Even while using protection, couples have become pregnant due to failure in their contraception.
If you do not start your period on your next due date, then you may give yourself a few extra days to see if it is just late, and if it still doesn’t come you will need to get a blood test done at your clinic. They are the most accurate and will eliminate any false readings from home pregnancy tests.
