Its really up to yhu at the end of the day if you feel like you making a mistake keeping the baby then do what's best for u
If you feel like abortion is your best option then do it
That little thing growing inside of u is a life. U may think have f'd up but its not the babys fault. There is always the option of adoption. Give it a chance. U never know halfway thru ur pregnancy u may be so in love with ur baby u will have wondered how in the world u could think twice about it. But it is ur choice... pregnancy is beautiful. No matter who u got pregnant by.
Pray about it because both are life changing decision that you will love with for the remainder of your life. I believe the right decision is the You make from your heart
We have options. You do not have to have a baby you don't want. Or you could opt for adoption. let me know if I can help sweetie. good luck
