i have an eight month old son. and im thinking i could possibly be pregnant again. i had gotten my period about 3 weeks ago. my periods are always irregular though. like the day before i got my period i had unprotected sex a few times and my boyfriend didnt pull out. then about 2 weeks ago the same thing happened. i feel pregnant. but im not sure if i would feel symptoms yet because i didnt with my son..but ive been feeling really naseous to the point i dont even want to eat, im having hot and cold flashes, headaches sometimes, and im really tired. is there a possibility this could be from pregnancy? or is it too early to tell?
