If you don't know how far along you may be, call your doc for an appt to talk about it and plan your ultrasound. They will try to date your pregnancy from your last menstrual period that you know of, so try to track it on your calendar so they can roughly estimate how far along you are cuz they try not to schedule your first ultrasound till Ur around 8-12 weeks.
Yes make one now and check and make sure everything is growing fine and if you are using medicaid apply now
Go make an app as soon as you can. The sooner the better dont you want to know how far alkng you are lol
