How can I tell my mother I'm pregnant?

How? be calm, explain to her the situation. If she gets upset, make sure that you're still calm and try to answer her questions as well as you can. She might be shocked and upset first but once its set, she'll come around and you two will have to discuss the situation.

Don't beat around the bush and be straight up honest with her. If you want to try and build up the conversation, just discreetly ask questions about pregnancy and later tell her you're pregnant.

As i don't know your mother personally its hard to give an exact answer, but i would just be honest and tell her in a calm environment, and let her express her emotion and her feelings, and just be honest with her about it. :)

Congratulations! I think if you approach her with humility and just be yourself and say, "mom, I am pregnant." I think this is a great start for the conversation... -Robert-

You should say, "I have something difficult to tell you. I found out that I'm pregnant. This is important to me and I may need your support."

You should do it in a comfortable place for both of you, and remember that she wants only good for you.

Your mother is going to find out you are pregnant either way. So, it is best to tell her before she finds out on her own. Go and tell your mom and be honest with her explaining why you did what you did and who you did it with (though you do not have to tell who you did it with but it is best to). She can respond in a number of different ways. She could either accept it and actually be happy to help you care for the child, or she could be upset. Either way she is still going to love you no matter what. She will never be mad at you, she will be mad at your choice. Even if she is upset at first, if you give her some time she might come around and be alright with it. Some people react differently to things that are so sudden and later regret how they reacted.

Sit her down and calmly tell her. You want to have an adult conversation where both sides are being mature. If she gets aggressive or loud, walk away. If that is not an option, look for a way to escape. Remember you have another life to care for now.

Explain that you need her direction and advice. Be willing to listen to what she says and think carefully about it.

Start by sitting down with your parents when their in a calm mood. Remember that you are their daughter and they'll love you no matter what, even if they get mad and say aggressive things. Theres no other way to tell them then to just let it all out. Explain the important things to them.
