Pregnancy

So, me & boyfriend have sex & most of the time it's without a condom. I know you should always do it with a condom cause no matter how good he is at pulling out it CAN still happen I do realize that & we do it with a condom when we have them. I Don't want to sound like a nymphomaniac or anything (cause I'm not 😂) but unfortunately we do run out , more often than not & we go ahead & just do it with out it cause of the moment and ect. Now if I do indeed get pregnant one day (let's hope not knock on wood I'm not ready for that just yet I wanna finnish collage first ) I'd like to know the symptoms you'd get, maybe the day after or immediately & whatnot. Just so I can act fast and  at least get plan B or something. I know a lot of girls are against abortion & i understand that if you do the do that's what you get but, like I said I want to Finnish collage & actually get stable in a job first before I have a baby & not make it go though the stuggle & if you catch it early enough it won't suffer or anything. It doesn't really remember much of anything. I'm not trying to insult anyone or say anyone's wrong it's just my point of view of it.
