Does it sound like i'm pregnant?

I had s*x wit my partner last night and wonder if it is possible for me to b pregnant we have been together 4 1 month now and have been on the pill but have also been on antibiotics after we had s*x I came on my period but have certain symptoms such as...

as tierdness, feeling sick, and certain smells that I can no longer stand that make me feel sick such as the smell of alcohol and certain foods neither me or my partner would be bothered if I became pregnant as we are both ready to take this step in life

you could be as on rare occasions people can have periods throughout pregnancy. but i doubt you would have these symptons the day after the night before like straight away. plus if you were on the pill then i doubt it was possible. unless you had an upset stomach or was sick due to illness a couple of days before you had s*x which may of made the pill not work. then its not likely you are.
