Hey guys, just wondering if this has happened to anyone else. i was 5days late for my last AF

, tricky lady, and i am currently on cycle day 18. i usually have 33day cycles and usually get sore boobs about 3days before AF is due.
I am currently about 16days off AF. What tha????
Has anyone experienced this?
Please repond any info or personal experiences will be very helpful.
I had a bit of a strange period when i was five days late. It didn't last very long and had quite a few clots in it. i have no idea. i already feel a bit bloated. i dont think that i could be pregnant as i took a PG test the day i got AF and it was BFN.
Is it possible that i ovulated extremely early and AF is coming early too???
