Cycle day 50 but negative test

[JC17fj74]

I'm on day 50 today and have taken two tests one Monday and another yesterday both negative. This is a long cycle even for me, I can be anywhere between 35-41.
We had unprotected sex on day 1 of my cycle and days 44 & 46.
I'm really worried I may be pregnant, but going off the days we had unprotected sex i keep telling myself it's unlikely 🤷🏻‍♀️
If I was pregnant wouldn't it have shown up on a test yet?
And if I'm not then what reasons could my period be so late?
I'm so confused and anxious.
Any advice please no hate 😢 xx

From those dates it would seem incredibly unlikely. Any idea which day you ovulate? Sperm can live for 5 days so it would only be possible if you'd ovulated on CD6 which would be right after your period or CD43 which is also unlikely.

CD43 onwards

I don't know when I ovulate no 😢 I still haven't had my period yet.
