U.S. bee here.  I had my regular gyno do a blood test because I found out in my 4th week of pregnancy.   My midwife would not see me until I was 8 weeks and didn’t have an opening until I was nearly 9 weeks.  The blood test from the gyno wss not fasting.  My midwife ordered an ultrasound and that was the verification.   I had another blood test to check my oversll health shortly after that.

emibee :  looks darker to me.

The line closer to the urine stream is the one that should be darkening, which it is. Pretty soon it’ll start getting lighter, however, because of what’s known as the “hook effect”. Google can teach you about that if you’re curious.

The GP will likely have you pee on another stick.  I know in some countries with universal healthcare you don’t actually see an OB until you’re further along than what you do in the USA, so your GP may take care of you for a bit.

You’re very much pregnant lol. Tests only have a limited amount of dye in them so as you get further along the test line starts to pull colour from the control line. 

But the hook effect is real so I’d say stop testing now. 

Good luck at the docs. I’ve a friend in Australia pregnant at the moment and she said the booking in with the midwives isn’t until 16 weeks (is her second though so might be different)

It’s pulling color from the control line. You’re definitely pregnant.

My OB doesn’t even bother with a blood test unless you’ve had losses in the past. The urine tests are extremely accurate and a false positive is pretty much unheard of.

emibee :  in TTC Land we call that “beating the control” which is what you want! So, you’re 100% pregnant. Like

amanda1988 said, you can Google the “hook effect”– but seriously, once you go down that rabbit hole it’s hard to get yourself out of it. Plus, there comes a point where test progression really wanes and you’re right about at that spot. Since you haven’t been testing daily since 8-9DPO and following it up through where you are now, *I’d* stop so you can save yourself some sanity. Take it from me LOL.

emibee :  If I were you, I would really try your best to stop Googling about miscarriages and other worse case scenarios. The Internet will always show way more horror stories than are probable because people tend not to post about their perfectly normal pregnancies. People post more when something goes wrong. Online forums will make even very rare situations seem common due to the selection effects.

Yes miscarriages are not rare, but the majority of pregnancies are lost before one even realizes they are pregnant. The further along you are, the less likely a miscarriage is. You’re most likely already 6 weeks along. Most pregnancies are normal.

Try to get your information from government health sites and other reputable sources.

The reason why most doctors won’t see you until later is because there really isn’t much to do in early pregnancy. The vast majority of miscarriages can’t be prevented. They are a result of abnormalities in the embryo and not because of anything you did or didn’t do.

You are definitely pregnant based on your multiple tests. See the doctor for peace of mind if you are very anxious.

Blood tests are fairly routine in Australia. Not so much to confirm the pregnancy, but they like to do a full blood work up for vitamin levels, immunity etc. They will also obviously confirm the pregnancy too.

As others have said, your test is actually getting darker! Eventually it starts to pull colour from the control line. That’s a good thing! Line strength isn’t a good indication of pregnancy viability anyway, and your line is already way too dark to do any decent comparisons, so you can stop peeing on things now!

Bee, I think you’re looking at the test upside down! Your test line is getting darker, and is pulling dye from the control line as PPs have said.

Do stop testing at this point as the test will become unreliable because your hormone level is too high.

In the UK, no one confirms we’re pregnant for ages! We get a midwife appointment at about 8 weeks and the scan at 12, nothing before that! With those tests, try and relax and enjoy being pregnant.

Being on forums can make you feel like successful pregnancies are a lot rarer than they are – remember, the odds start off in your favour and get better and better every day.

I never really celebrated getting pregnant as I convinced myself that making it to 12 weeks on a first pregnancy (or without having suffered any miscarriages/CPs) was unlikely. I’m now coming up 15 weeks and wish I had!
