Potentially pregnant clear blue -one reading faint positive and two not

[Cutekitty]

Hey guys messaging again. I still haven’t got my period it’s been 3 weeks since stopping the pill. I did a test this morning and looked at it within 3 mins and checked it at 10 mins and got this (faint positive) and then I did two more close after each other and they are both negative. Just wondering what that means. Also just had an internal ultrasound and external ultrasound and nothing showed up on it but I only had unprotected sex 1-2 weeks ago. Feeling confused

Close up on the positive… is it just an evaporation line ???

Why have you had an internal and external ultrasound when by your dates you're 3 weeks off the pill and had sex "1 to 2 weeks ago"? How did you get that done? You're too early to even be testing. Nothing could have been seen internally never mind externally.
For a start, begin to track your cycle and the days you've had sex. There are apps for this.
Read up on how conception works and commit to monitoring your cycle. Did you even have a period after stopping the pill? I think there's a lot you need to look up and learn from.

I had an ultrasound because I am known to have endo and also my gynaecologist asks me to do regular ones. I also had unprotected sex 3 weeks ago and a month ago but 2 weeks was the earliest since my last test. I haven’t had a period no but I was on period delay medication not technically the pill. Hopefully that’s more helpful. And sorry if I hadn’t explained it well

I don’t trust clear blue tests, do you have any pink dye tests?

Hi OP. Please don't bother with Clearblue tests when you're testing early. They're notorious for evap lines which I believe these are- I cant see anything on two of the tests and on the one you posted alone it's an evap.
I agree with LoneGoth about the advice on starting to track your cycle.
