Well I used to come on here and post all the time when I was pregnant with my son. He is now 20 months old and his father and I have been together for almost 5 years ...I'm 19 and he is 21.. I will be starting college in the spring, but recently I have been having some strange symptoms as if I was pregnant again.. I recently was put on antibiotics and I am also on the pill I was never given a paper that said my antibiotics could cancel out my birth control.. My question is when u are pregnant for the second time do the symptoms appear sooner than with the first baby? I have been feeling tired, and been feeling sick in the morning but my period isn't supposed to start for another week.. I was just wondering.. thanks
