Tips for me and my husband to conceive?!

Give me all your tips about conceiving for the man and woman! Myth or fact!!

-My period started Feb 15th and my cycle is roughly 30-34 days

-My first and only son was born April 1st, 2019 via Csection due to breach position (don’t think this matters but just in case!)

-Glow is expecting my fertile window to be March 3-9

-First response ovulation calculator on their site predicts fertile window to be March 3-7

-ovulation tests, do these work?? What brand? When would I test?

-just started trying for baby #2 in January, but really no method, just not using protection so far

Thank you in advance ☺️
