When should I see a doctor?

Lindsay

I had a miscarriage in May, a d&c June 18th and had a period right after. Another on time regular period in July and now here it is.... 8 days past my usual period and nothing. I’ve been getting negative tests so I’m really just confused. When would you call the doc and see about coming in etc? I’m just nervous they will think I’m crazy or something since it’s only been 2 months since my procedure. Thanks ladies :)
