I had intercourse on the last day of my period ...

I had sexual intercourse with my boyfriend on the last day of my period (10/23), I was very little, we had sex without a condom and he came inside me, I take contraceptive, but I only took it 3 days later, I had a morning ... I'm not up for nothing, I have no appetite and everything I eat has no taste, even tried to drink a glass of milk but did not come down, can I be pregnant?
Expert answer:

She may even be pregnant, but it is very difficult for her to be in this relationship because she was menstruating and takes contraception, and pregnancy symptoms only appear from the end of the first month of pregnancy.
