I had a baby girl. It will be seven weeks this wednesday. When can I start bedikah? What day is the earliest i can go to the mikvah if i’m clean? Thank you.

Shalom U'verachah, Mazal Tov, generally we do not hold by the Torah law of a specific waiting period after giving birth, unless you have a specific family minhag to do the opposite. Therefore when the bleeding has ceased you can check for seven clean days and then go to the mikvah. Kol Tuv
