Started prenatal vitamins yesterday! Here we go...

Hi everyone! I'm new to Glow! Started my prenatal vitamins on Oct. 1 (yesterday) and plan on stopping my BC pills on Jan. 1! Glow is telling me that my first O after that is Jan. 11th but of course that'll be too soon. Just wanted to know some tips from you all on how you're prepping? All comments welcome on what to expect and how you all prepared for your BFP while taking prenatals
