Need help finding a book

Ooh okay

I dont think its a series. I'm not exactly sure what the nature of the job was but I think secretary? There's another random scene I remember where the main female character shares with the main guy that she was drunk at a frat party and thats how she got pregnant. But our main guy is wholeheartedly participating in the pregnancy. There's a 'uh oh I'm bleeding' scare too? I'm sorry I only remember snippets of the story.

I really hope you do because it's been like a brain itch, it's going to bother until I read the whole book again.

She's Expecting by Barbara McMahon is the one I was thinking about. I remember that the h got a job as the H's secretary at his construction business. I can't remember how far she was along in the pregnancy, but the father wasn't involved. I remember she started bleeding and the H took care of her.
