How soon should a blood test show pos after implantation? I had what I thought was implantation bleeding on May 26 took a blood test on May 29 and June 1 both should a very low hcg level, which I understand is a negative, but was I testing too soon, still no period but I had some break through bleeding last night into today but has already stopped, Is this common. I still feel like I might be pregnant with the sore breasts (very itchy too), lower stomach and back cramps, headaches mainly at night, and major fatigue. Some nausea here and there but not too bad, constipation, and heartburn and hickups frequently. Maybe there's something else going on with me that's not pregnancy, I don't know, going back to the DR for another blood test this Thursday, anyone have any input on what may be going on with my body, oh also, I do have endometriosis and a tilted uterus, I believe it tilts backwards. Just want so opinions on to other causes besides pregnancy I guess, just impatient on finding out what's going on with me, thanks

You won't get a positive for at least 2 weeks after intercourse, sometimes longer.

Thank you Charolotte234s I actually just read on the internet that it takes on average about 11 days after conception to get a pos result on a blood test and 11-14 days after conception on a urine test, that's when the hcg are usually high enough to detect. Now if I implanted on May 26 though, when did I conceive on average, basically my question is, how long after conception does an egg take to implant? I couldn't find that answer myself, thanks

The egg will usually implant within 4 days, but implantation bleeding is inaccurate and it's not even assured that the spotting some women get is implantation bleeding.
