I’m having an identity crisis

So... i think I’m gay/lesbian but I’m not totally sure?? I have been identifying as pansexual but the last few weeks i have been thinking maybe not? I have dated and had sex with women in the past as well as men. But the thing is I’ve been in a relationship with my kids father for 3 years and we have a daughter and I’m currently pregnant with our second daughter 😳 i do love him and want to be with him. But i don’t see a future with him anymore if that makes sense. I also can’t see myself with another man if we’re not together anymore. I have been having fantasy’s and dreams about being with women. I just really want to be with a woman again. Or maybe i want both?? Like i want him and a woman at the same time. I’m so confused. I’m 24 so i thought i would have had all this figured out by now. It’s so strange having to think about this when i thought i was just pansexual. Should i just give it more time and think about it or should i tell my boyfriend I’m having these thoughts and feelings??
