When is my due date?!

Question

My last period was around 15th December and I had finished by 23rd December, I'm so confused I'm getting told different things and I'm so impatient I just want to know but don't know how to work it out?! Some people are saying I'm due September and some October, can't work out how many weeks I am?! Could someone please help me and explain? 
Thank you Xxx

Answer

September 21 unless your doc says otherwise. My last period was December 16 and I’m due September 22 which even my dating scan showed almost down to the day (I was two days behind).

Answer

It depends on when you ovulated. Your dating scan will give you the best idea when you are due. It’s all just an estimate regardless.

Answer

You will know at your dating scan. It really depends on when you ovulated.

Answer

My LMP was December 19th and I’m due September 25th
