Are you female? Have you been pregnant?
Going full term /sucks/
Look up all of the side effects, and then tell me "Yes, I want to go through that BS to save a life that I may never get to know, and it may not even want the life it is given"
If they are in schooling age espc, Congrats, you just told her to throw her life away, and put the kid in the likelyhood of an equally hellish situation with a high chance of birth defects.
Are you basing that off the mother abusing her body when she's pregnant?
Also @OP there is basically 0 chance your gf is pregnant if you use a condom and all she has is tender breasts. Most of the time women won't even realise they're pregnant until they miss a period. So stressing about in when its <4weeks since last period is crazy silly.
Also at 23 your life should be set-up well enough to take care of a child, i suggest you focus on achieving some stability.
