14 years old and pregnant... again.

Please don't comment anything rude because I am already hurting emotionally from this & realize I need to make changes regarding my responsibility with sex. 
I found myself pregnant last year during the fall time, my due date was to be in May. I have a boyfriend of two years & this is who it was by. My mom pressured me into an unwanted abortion & said that if I didn't she wouldn't help support the baby etc. After my abortion I was sad and confused, now I realize it MIGHTVE been for the better. 
Now I am pregnant again, I am 8 weeks and two days & just found out today. I am scared about telling my mom because I know she'll order me to get another abortion, which this time I'm considering. I am confused whether or not to keep this baby. My boyfriend is fully supportive of either decision, he's 16. 
I just need someone's opinion.. or a little (nicely worded) advice. 
I was on the orthoevra patch at the time this all happened.
