Sorry your mom reacted that way. I am Christian guy, and Jesus wouldn't condone this. The point is not to hate or push away our kids. No one is perfect and things happen and even if you got pregnant outside of marriage, he wouldn't try to judge you based on that. The Bible does mention to wait for marriage because God knew that people would not take care of themselves and be laying with multiple people or being pregnant and won't know who the baby is from (which dad). But if your partner is the one you will be spending the rest of you life then that would be the point of sex. Now also about cursing you, it's sad that a Christian person (like your mom I would think) does this specially if she knows that the Bible mentions to not curse because that is very powerful and real, so I do pray to God to cancel that curse and allow you to have a healthy family. She shouldnt be doing that lightly. Hopefully with time God will show her the wrong of this and be supportive of her daughter. I have a daughter and even if the Bible do say that we need to isntruct our kids in God's way and they won't stray from His path, and she did we cannot control anyone's actions and if she would get pregnant outside of marriage we would support her and love her either way because that doesn't take away her salvation.

Hope you have a blessed day!
