In need of advice

I recently split with my abusive ex, we dated for 4 years and had a little girl two years ago. We broke up about two months ago, and I’ve been on my own just trying to get my life back, I found this extremely nice man. He’s amazing, and treats me like a queen. We’ve had sex only three times and once was without a condom, and it just so happened to be while I was ovulating. There’s a chance I’m pregnant and I’m terrified, he’s totally excited as he’s wanted a child,but we’ve only known each other for a couple weeks, and I’m so afraid of how people will judge me for having two kids with two different fathers at the age of 21.... I feel like a bad person.... I don’t know. I’m also afraid of how my abusive ex will respond as he was physically abusive and I still have to see him because he wants to be in our daughters life.. I don’t know what to do.
