Has anyone else experienced this?

I think I've messed up my body 😫 I've been spotting for 4 days, my period was due yesterday & it's never been like this! Since I can remember my cycle has been on schedule and normal. I was looking at the bright side that I'm always on track but now I'm just lost! 😭😭😭 lol do you think ttc can change your cycle?
