Setting myself up? Sleep

I am a NIGHT OWL. Even more so that I’m pregnant and not working. However, even I will say it has gotten a bit out of control. I am up till 3AM or later and sleep till 11am-12pm. Am I setting myself up to have a baby that doesn’t sleep at night? Due in 8 weeks and trying to prepare myself. It obviously wouldn’t bother me much but I worry about my significant other who has to get up early for work. Am I going to be sleep training myself & a baby?
