So i have a three year old son. I havent been in any birth control for the past year. Recently, i had unprotected sex with my boyfriend n he *** inside of me about two weeks ago. Then today again. I know is dumb, we thinking about having more kids but then again i have back down. Im trying to finish school and go back on active duty. Can i be pregnant? I have my period about the third week of the month n the days of duration vary if i do physical training from 3 to 6days. I need help, am losing it! Starting to have cramps, feeling like i need to puke, very sleepy n tired. Yet my last preganancy i had no type of symptoms just i missed my period. Can it just be in my head?
