Best position after sex. Advice etc

Erika • Expecting first baby August 2019!!

Hello!

My fiancé and I have recently started trying to get pregnant, this will be our first child. I have read a lot about the best positions and ways to keep his sperm inside me right after sex, but I’d love to hear advice from others if your comfortable sharing!

I also recently started taking prenatal vitamins, any other vitamins moms have taken while trying for a baby? First baby specifically?

Thank you!!

Erika
