How soon can a doctor's blood test tell I'm pregnant??

I don't expect to get my period for another week...but I've been so crampy, extremely lightheaded, and I've got the sore boobies. We just started TTC, but I know it's too soon for a pregnancy test. Does anyone know how sensitive a blood test would be if I went into the doctor? I spotted a little bit about a week ago, which NEVER happens in between periods...which I'm starting to think could be implantaion bleeding? Please let me know if I were to go into the doctor, if they could tell from a blood test.?.?

  • The truth is that it all depends on your cycle and if your body is producing hcg. Even with a blood test it can still be too early. I had a test done on cd25 and it came back neg but my doctor wants me to retest cause we have no clue how long my cycle is but Im just going to do an inhome pregnancy test on cd31. Gl and lots of baby dust!!!

  • I had mine done 11 days before my period and found out I was pregnant. I'd call your dr.

  • most doctor's blood tests can tell as soon as 4 days after conception, at least that's what my doc told me. good luck!

  • Ok, so I called the doctor and they said they normally don't do blood tests to see if your pregnant and that I should wait till my expected period to take a regular test...
