Should I be worried 😟

I'm on cycle day 43 with no AF.

I'm definitely *not* pregnant as the last time I had intercourse was March 27th so that wouldn't be a concern.

Last AF I had was April 11th-15th with what I remember logging in app as brown spotting, it was definitely heavier than spotting but just a dark brown for 4 days.

April 26th I logged that I spotted lightly pink for a day which I assume was that mid cycle spotting people sometimes get.

Now I'm still waiting for AF with zero signs of her coming, should I be calling my obgyn tomorrow 😵‍💫?

I took a digital test yesterday just to be sure and of course it's negative so I'm not sure what could be causing this 2 week late whatever 😅

Any pointers on what it could be so I don't drive myself crazy with Google while I wait for tomorrow?
