A faint positive pregnancy test

Hi I'm 26 I have a boyfriend and we have been together for 1year. We have unprotected sex as I lost my birth control pills 6 months ago. I did not get my period month, it should have been on 11th June, so I took a pregnancy test. The first one showed two lines 1 very faint and two day after I took a second test it show 1 line and so I wait a week and took another clearblue one and it show not pregnant I don't know what's wrong but I'm feeling strange.

It can be confusing when a pregnancy test appears positive early after a missed period. The rule usually is that if the second line is very faint you repeat the test a week later when usually the hormone level will be higher if you are pregnant. Sometimes a test can show a faint positive but not be an established pregnancy.

If you are concerned or feeling unwell I would make an appointment with your GP. They may advise a couple of HCG blood tests to get a more accurate idea of whether you are pregnant or not.
