40 days cycle and no period, strange clear blue test

[222anna]

My periods are always regular like clock work between 28-30 days (usually 28 days though) and I’m now on day 40 of my cycle - I’ve never gone that far and I never use hormonal contraception. Me and my partner only use condoms. (No judgement please my body just doesn’t agree well to any pills/coil etc)
I did a clear blue test and it looks like a positive at first glance but if you look carefully, the line is on the left a bit and doesn’t exactly look like it’s meant to be part of the positive? I did two clear blues and they both did the same.
however on the pink tests it comes out negative?
super confused as when I was pregnant with my dd I had a positive after only being 5 days late on a pink test.
Any clue what it could be? Pregnancy or something wrong with ovaries? Just never in my life been this late before so I’m a bit worried!
Got a doctors appointment but they’re still using Covid rules so it’s over the phone and I’m going away on holiday on Saturday so I doubt I’ll have time for blood tests or scans - don’t want to go on holiday with a 4 year old stressed and worried 😅

If I were you I'd get a digital test clear blue and first response do them they've always been accurate for me

That looks positive to me ..

To be fair @Onlyrainbows is right if it was my test I'd assume it was positive

Mm did it come up within the timeframe? If not could be an evap?
If within time I’d say definitely positive. Strange first response isn’t picking up on it though….
