HUH?!

I'm 10 weeks pregnant and have been having some craaazy dreams. I don't even have anyone in my personal life I can tell this to because it's so off the wall for me. Anyway, I'm 100% straight (or so I thought) and lately I'm having dreams of kissing and making out with other females. I don't know any of these girls in my dreams. They're just random people I've never seen or anything. Well, the other night I had a dream I asked Harley Quinn if she wanted to make out, lmao. Anyway when I wake up I'm soo turned on by these dreams I actually got online and watched lesbian porn. Like, wtf is wrong with me? I have never been attracted to a girl before or even thought about doing anything with a girl or even flirting with one. I've always been about the D. Is this because of the pregnancy or what? I don't even want to tell my husband about it. I just don't have anyone I can talk to about this.
