When did you stop vivelle patches?

6-7-8

I'm only 5w2d today and my doctor is having me stop the vivelle (estrogen) patches tomorrow. I did 2 patches every 3 days, up to 10 times. They say this is all I need and I trust them but nervous to remove and stop them tomorrow. This is my first pregnancy, I had a chemical in Jan from a Fet which I didn't use patches. When researching I saw a lot of people don't stop until they stop PIO at about 10-12 weeks. I will still be doing PIO until abour 12 weeks they said ( depending how it goes). Anyone stop vivelle patches early in pregnancy and still pregnant etc?

 Thanks for your help in advanced.
