Can some one help me figure out how many weeks I am. I got my positive pregnancy test on the 21st of August. And I had taken a clear blue digital weeks estimator test that day and it said 1-2 so would that be o conceived most likely on the 7th of August? I didn't have a cycle in July but apparently ovulated late my man was out of town working all of July and we didn't have sex until the 6th - 12 th of August . So what do you all think?? FORGOT TO MENTION THAT I GOT MY PEAK OPK ON AUG 10 &11 TH
