First pregnancy test positive, then negative

Same exact problem here.
Last Thursday I tested because I felt extremely tired and had a heavy feeling in my lower abdomen.
This test from Action (early with sensitivity of 10 hcg concentration) turned positive right away! It was indeed a faint line, but it was clearly there! After the mentioned time, I hid the test from my partner. I quickly made something nice at work to tell him that we're expecting. I wanted to stick the test on it, but that faint line had completely disappeared. Then I started to doubt.

Today I did another similar test and this one is negative. I'm testing early now, since I'm supposed to get my period on Monday.

Who can help me? Or is it a pregnancy that wasn't successful?

Christine, I hope you've had a positive test in the meantime?

Hi ladies,

I used a test strip 5 days ago, and it was immediately positive (dark). I did it again the next day, also positive (I know it's not ideal to test the next day, but I have a copper IUD...). On day 3, I tested again, and it was lighter. Now on day 5, today, the test is almost negative... Can it change that quickly? Was I pregnant? I'm supposed to get my period in 2 days.

Hi!

I have a question and I'm totally unsure...
I did 4 tests yesterday (yes, I really wanted to be sure) all from the same brand. All 4 were positive.

Now I did 2 more tests today (from the same brand and a different one). These tests were negative.

How can that be? I read everywhere that getting a false positive test is rare. But I also find it a bit weird that you test negative the next day.
I'd love to hear from you! Thanks

Hi. I'm having the same problem. For a good week now I've been feeling really tired, getting headaches, and my breasts are very tender. Yesterday at 9dpo I saw a faint line on the pregnancy test, which was clear in the photo. I also went to the doctor and had blood taken.
This morning I took another test and it was negative, and the blood result came back negative too. Well, the doctor says I'm only 10dpo now, and normally you can only see it in the blood from 11dpo?
I don't know anymore. I'll just wait until Tuesday to see if my period comes or not.

Hi,
I had a positive test from Kruidvat on March 30th, then immediately did a Clearblue test which was also positive!
On Monday I had light bleeding, which stopped after 1.5 hours.
Now I'm testing negative.
Help me!

Hi everyone,
I had a positive test 4 days after my ovulation and now 4 days before my period, I tested twice and got negative results. In between, I also had some light bleeding. What could this be?
