Advice please ladies

Good evening girls. So I'm 19weeks pregnant and over the moon. But I need help and advice. My hubby cheated on me at the start of our relationship, I fogave him and everything has been fine but I'm now finding myself not trusting him again and getting worried. I don't know if it's the hormones or what but has anyone got any advice. Have any of you forgiving a cheating parter? Xx
