Needing to vent

I'm officially 18 weeks today I had my appointment yesterday, got my flu shot etc, however the technician wasn't in when my appointment happened, and not once have I had an ultrasound. The only ultrasound I had was in the ER finding out I was pregnant. I thought between 16-20 weeks you found out what you're having which I've been anticipating since I found out, but the nurses seriously seem not to give a fuck if it doesn't fit in their schedules. I'm getting kind of upset because we've been doing monthly visits, which my boyfriend has maybe gone to one of them. He lied about working and hung out with his friends all night doing whatever. I honestly feel like I'm about to go through this being a single parent and I think I'm more heart broken than worried. I'm honestly just so down this past week, just had to get this all off my chest 😓
