Going insane!!

I'm 8 days late for AF and I'm still getting BFN's. I'm NEVER late like this! I'm making myself crazy wondering what is going on with me. šŸ˜ž I was due for AF February 27th. Nothing came. Had some cramping and thought for sure she would show her ugly face. All weekend, nothing. Monday, I had some light pink spotting once after going to the bathroom so once again I thought AF was on her way. Now almost a week later, nothing. My boobs hurt, some cramping but not like AF cramps they're much more dull. I've been dizzy off and on and my lower back is killing me. Anyone else in the same boat?! I just want my BFP or for af to come so we can get back to ttc. šŸ˜£
