Not sure what kind of input you're looking for... are you asking what we thinking is going on? First of all, sorry for your loss! Chemicals suck, but I do prefer those to miscarriage. Your husband is right about the testing for the sake of your emotional health, however, you mentioned that you smoke. Of course you know you should try to stop, blah blah blah. But it's not that easy, especially with so much disappointment. I'm sure a bfp is a huge motivating factor to stop smoking, so testing early can be good because it let's you know asap if you have a baby on board and need to try extra hard to resist. All of that being said, perhaps the chemical can act as a motivator as well. In memory of that loss, you could channel your sadness into determination to stop smoking, which will increase your chances of a bfp, and more importantly a healthy baby that makes it full term. You really can do this!

This is just what happened to me...I had a negative blood test at 3 weeks pregnant..didn't get a positive until around 5 weeks pregnant so it is possible. 

I had never heard of a chemical pregnancy until I had one in August. I bled like normal period then in September I found out I was pregnant again. You could very well be pregnant again just wait until you miss af. Good luck
