First ultrasound

For those of you that got your first ultrasound after 11 weeks, what was the reason? Or if your not that far along, when are you planning on getting your first one? I'm just a few days away from being 12 weeks & I'm still waiting to get my first due to not having insurance (don't qualify for help from the state) and the money at the moment to pay out of pocket. Just curious if anyone else had dealt with this situation or something similar. Waiting on insurance that should be starting within the next month.
