My (18M) gf (18F) agreed to having sex without protection

Let me explain the situation better. She's currently in her ovulation period with her periods starting the next week. Now obviously we both know currently is a very risky time to have sex. We've never had sex before and today while we were kissing, I casually asked her if we should have sex expecting a laugh and frank response but she actually agreed to it w a serious face. I asked, what about protection, she proceeds to say we should do it raw (and she was being serious). Only I know how hard it was to control myself from doing it knowing the risks of getting her pregnant. After we reached homes after our makeout, I asked what she would've done if I got her pregnant, she replied that she'd proudly keep the baby and that "agar aisa kuch hua to ham dono sath me bhag jayenge".

Man, this was a veeeryy huge commitment from her side and now I feel like I have to protect this girl at all costs. If somehow things went bad between us and we had to part ways (i hope this never happens), idk what she'll do, it's her first relationship and I don't want to think what anyone else might do to her and take her innocence's advantage.
