New to forum, new to Clomid

Kira
Hi ladies,
Looking for a community of support. My husband and I have been TTC for a year. My cycle length is 40 days and I typically ovulate on day 29. My acupuncturist + physician are recommending I go on clomid to boost my egg strength. 50 mg. My doctor is recommending I start on day 5, but my acupuncturist is recommending a start on day 2 or 3. Any insights, expertise or tips you can lend me on which day to start?
