I am a little confused and I hope this doesn't upset you but i'm just wondering that if you're against abortion why do you think it's the best option for you? I know bullying can be a dreadful thing but if this is the only reason for your change of heart then it's probably not for the best.
I am pro-choice but you need to be totally sure that abortion is what you want before you take that option.
It entirely depends on where you are whether you're too far along for a termination. I'm in the uk and they're allowed up to (and including) 24th week (or anytime for danger to the life of the woman/severe fetal abnormalties). At 15 weeks the procedure is likely to be a d&e (dialation and evacuation) which takes place over 2-3 days
i've explained it in the most simplistic form - in all honesty i'm sure there will be some graphic resonses from some pro-lifers but these are just the facts of the procedure without any emotional manipulation.
(the cervix is numbed and dialators are inserted, these expand overnight, then the uterus is cleared and finally suctional aspiration)
in all honesty it sounds as though you're against the idea of having an abortion. You need to do what is right for you and terminating a pregnancy because of bullies doesn't seem to be a good decision imo
nb d&e not to be confused with d&x (referred to as partial birth abortion) which is not used until later in the pregnancy and, whilst it sounds horrific, it's usually done in this way to for maternal reasons.
