Chemical Pregnancy/Early Miscarriage

Chelsea
I had a chemical pregnancy in late June after having just come off birth control. I took several pregnancy tests that came back positive around the 35th day of my cycle but then began bleeding on the 40th day. I never "felt pregnant" as some do and I didn't have any pregnancy symptoms. The bleeding seemed just like a period. Does anyone have any experience with chemical pregnancies? Is it an indicator of what a normal early pregnancy would be like? What does it mean in terms of getting pregnant again? Is it better to know you had a chemical pregnancy instead of thinking it's  a late period? Although very early it was tough for me and especially my husband so I am tempted to wait until it's been a week or two after missing a period before I'd even want to test again.  I have heard if you have 3 miscarriages you should  talk to your doctor, are chemical pregnancies considered in these?  I know I have asked so many questions but I am just so confused and don't know what to think. Any insight about chemical pregnancies or early miscarriages would be greatly appreciated.
