Dark OPKS 19 days late on CD 54

Ac

My period is late by 19 days.. I’m on CD 54 since my first period.. I took a test around 9-10 days late an my HCG tests were negative! I had a lot of odd things happen to me that really made me think I was pregnant but I decided to wait for my period ... WELL she’s still not here. An no sign of her. I don’t have PCOS. I’ve NEVER missed a whole period before! I took an OPK around the 11th an 12th of July an I had very Dark opks but stopped testing. I’ve been to scared to test again so I took two opks an they are this dark? Plus it’s night time here an this wasn’t 4 hour held in pee. I’m so confused! I also have ALOT of CM an have had ALOT of cm for ages now. We been trying for over 2 years so this is just rude of AF to be messing with me like this! 😂 I really need to know what’s going on!

These are my 19 day late OPKS
