So my boyfriend and I have had sex 5 times in the last week. The only birth control we used was the pull out method. We both know that this is stupid and know the possible consequences. Its been 7 days now since the first day we did this and I threw up twice yesterday and once this morning. I am also getting winded easier, im soooo tired and Im super cranky. I have a two year old and these symptoms are similar to what I had last time but it seems too soon to have these kinds of symptoms so strong. Is it more likely its a stomach bug or do you think this is pregnancy symptoms? Does anyone know the likelihood of getting pregnant this way? My period is due sometime this week probably thurs or friday.
