SOLVED. A fantasy series, HELP!! [s]

[Daniella]

Someone recommended this series on Tumblr but I forgot to write down the title. I haven't read it yet, so the details I provided may be incorrect. The books about a heroine who had superpower (or something like that) and joined a group of people who could train her. The leader of the group was a man who used dark power. They didn't get along at first because he thought her behaviour was suspicious. Then they understood each other and he trained her. They married later. During a fight, he gave her all his power and died. After that she discovered she was pregnant. There is a sequel in which she married again to an old enemy (who turned out to be a good guy after all).
That's all I can remember and sorry for my bad English. If it sounds familiar to you, please let me know. Thank you so much.

Some of it sounds like The Black Magician Trilogy and The Traitor Spy Trilogy by Trudi Canavan.

First book: The Magicians' Guild

It reminds me of Symphony of Light and Winter (Renea Mason) and also it reminds me a little of Land's End Trilogy (Melodie Campbell)
