I am two weeks late on my period coming up to three weeks yet I have taken 6 negative pregnancy tests.
I have quite a few symptoms which other people are now picking up on.
I am nauseous regularly but mainily when travelling sometimes just sat still and more as soon as I wake up and from around 4.30pm, I am tired which people are starting to tell me I look tired, My skin is playing havoc (I have never suffered with bad skin) My nips are more sensitive, I have like fluttery feelings in my belly and sometimes like a sea sickness feeling. I have 'baby brain' I blocked my bank card from entering the wrong PIN which I have never forgotten before, I have had a metallic taste 2x in my mouth. This is what I can think of the top of my head.
I have took all different tests from tesco own to clearblue.
I have booked in for blood tests tomorrow at my DRs but I will have to wait 10 days for results.

The more you stress and worry the longer your period will be delayed, see your doctor have a urine or blood test if your truly worried

Difficult to wait for the answer, but that is about all that you can do. For some women, a positive on a urine test shows up early, for others not for quite some time. Your doctor could also do an exam and get an idea if changes are occurring even this early. Fingers crossed that the results don't take the full 10 days. You could always try one more urine test at home, making sure to follow the directions carefully and using first morning urine, once you get three weeks late just to see if anything different comes up.

Pregnancy is obviously going to be possible, and you are experiencing some classic symptoms, but periods and hormones can be off sometimes as well. Hope it turns out how you would like it to!

Make sure, you are doing the home test first thing in the morning, with the first urine of the day. Some women will not test postitive on home tests until 2nd or even 3rd months, while not common, it does happen.

There are of course other reasons, which is why a doctor exam is a good idea

Sadly symptoms cannot diagnose pregnancy. Only a positive urine test, blood test, ultrasound, or giving birth, can determine if you're pregnant.

I'm afraid you'll have to wait those 10 days.

Good luck.
