This calculator has been designed to give you an idea of the treatment options available to you*. If you decide to have an abortion with Marie Stopes UK, one of our nurses will give a more approximate gestation date during your appointment by way of a scan.
*Please note that this online calculator will only give you an estimated gestation based on the details you have provided.

Please select the first day of your last menstrual period.

Our Doctors

I'm Dr Mani and I'm one of Marie Stopes UK's doctors.

Clients can have access to doctors anytime but usually I see them during consultations (when they first arrive for treatment) or when operating. 

You'll find our clinics are well staffed, well equipped and efficient. We can assure clients that the service they are getting is the best.

Clients can be emotional and scared but we treat them professionally and non judgementally. We make sure they are safe no matter what option they choose.
