Lost cycle?! 😂

I know it seems silly but I think I lost my cycle while traveling. I'm like clockwork every month but this month, it seems to have lost its way. I was hoping to have my "friend" (SO's nickname) before I left for my holiday but here I am, on holiday and no "friend" in site. Well, maybe not completely out of site. I had some spotting this morning when I wiped but after I wore a tampon most of the day, I removed it to find only a yellow staining and some slight brown colour. Then I decided after wiping and seeing the pink again, I would wear another tampon and the same thing. Only a slight staining of brown and not really a lot. I showered and wearing a pad but it just seems odd. My boobs are in on the game too. They were hurting earlier and then stopped then started again and yet again, have stopped. I'm not cramping like I would when my "friend" comes. Usually I cramp when I start to spot and nothing. Maybe I'm losing my mind?? Could flying and being further north than what I am accustom to be the cause of the delay?? Anyone have this happen to them?? Would love some insight. Thank you.
