Tmi and a long post

Hi, I have a concern regarding my period. So far I have all the signs I normally get, vaginal pain, cramps are lighter than usual, bloating, etc. But I did get my period or so I think. I was asleep, the pain woke me up it's usually quite painful so I went to the restroom and yes there it was quite a lot of bleeding since I don't usually bleed when I'm laying down. I've noticed these past periods that my period has changed usually the first day I get super dark red blood even when I wipe but lately it's been bright red and pink when I wipe. I thought today would be the exception and I be back to normal since I hadn't experienced the usual intense pain I would normally used to get and I did today but it didn't happen although the blood was intense quite a lot and deep deep red when I wiped it was barly there and it was quite bright and pink. So that was that. When about normal, until I had to use the restroom again. Still nothing in my pad and quite the minimum in the toilet and I noticed that what did come out was combined with egg white cm, which had never happened before. A combination of egg white cm and blood and it wasn't much. I'm experiencing the normal symptoms but it seems like my period is not going that way. I'm concerned? Has this happened to anyone? What could this be? What could it mean?
