Hi!
The embryo implants about 10 days after conception. When it implants it begins producing HCG which is what pregnancy tests detect, and also what causes the typical pregnancy symptoms.
Clear Blue First Response claims to be accurate up to 4-5 days BEFORE the expected period. So given all that information, you can decide whether to test or not. If you do decide to test, I would suggest repeating the test if you don't have a normal period.
I hope this helps!
Good luck!

I would go ahead and try to wait another week......I to tend to have ovulation symptoms early on sometimes......I know it is so hard to wait, we just want to see that BFP so bad! But testing too early and getting a BFN makes it even more stressful. Good luck and I am wishing a BFP for you!
