Due date


Hey y'all! So quick question. I just found out I'm pregnant (yay!) but prior to getting pregnant I didn't have a period for like June and July. The internet is telling me I go by LMP to configure the due date but considering I didn't have one I'm a little confused.

I conceived 8/12. Can y'all tell me how I figure this out and if this has happened to anyone else? Thanks :)
