Trying to conceive after miscarriage

Anita

So in October 2019 I stopped taking my birth control (the pill) because my fiancé and I were trying to conceive. I found out I was pregnant on Jan 5th 2020. Unfortunately, on Feb 6th 2020 we found out I had miscarried and I had a D&C on Feb 13th 2020. They originally thought I had a partial molar pregnancy, so they put me back on the pill but I recently got my pathology report back that said I did not have a partial molar pregnancy and there was only a mishap with the chromosomes. My doctor has suggested waiting until my 3rd cycle to try again. I started my first cycle on March 20th 2020. With that being said, when should I stop taking my birth control and should I take/do anything to help with conceiving and to have a healthy pregnancy?
