Early Pregnancy tips?

After me worrying about not being able to have kids after being told I have PCOS, my boyfriend and I decided to start trying...

It hasn’t even been a month and I did a test andddddd.....

Obviously the doctors were wrong! Did not think it would be so quick to conceive...

I know it is early days...but does anyone have any tips as to what to do now, foods to avoid, just anything I can do to help my pregnancy get off to great start?

I am taking Pregnacare- prenatal vitamins, but any advice would be really helpful, just feel a bit nervous....
