Can you get positive pregnancy test at 2 weeks 6 days - 3 weeks 1 day?

Question

Can you get positive pregnancy test at 2 weeks 6 days - 3 weeks 1 day?
From my last period I’m 7 weeks 2 days(October 31st). But apparently went for ultrasound today (which was too quick) and nurse say I’m 6 weeks 1 day(as of Dec 21st today). Thing is I got positive early, regular & digital on Nov 29th... so could they be wrong? Also my HCG on December 2nd was 87... on that date I would of been 3 weeks, 2days. So should I get second opinion or that may be right? Has anyone else had this happen before?

Answer

The week off is coming from the implantation window. Implantation of a blastocyst can happen anywhere from 6-12PO, with the most common days being 8-10DPO. If you’re 100% sure of when you ovulated, you probably just implanted late! Nothing to worry about :) good luck!

Answer

You could but it’s not likely unless you have a really short cycle. It’s normal for an ultrasound to be a week off. Doesn’t mean you need a second opinion. It’s not hard to tell age via ultrasound.

Answer

I got a positive test on 2 weeks 6 days, but my cycles are usually 25-26 days so I ovulate early in my cycle
