confused

5 days late. This morning I woke up peed at 4am went back to sleep woke up at 6 peed there was nothing I showered wiped and there was blood. I thought okay my period. I'm cramping . I have a pad this started at maybe 7 it's 9 now and there's not enough blood to cover the pad just little spots but enough to fill toilet paper when I wipe 😩😩. Any ideas what this could be ? Normally my first day is my worst day and gets heavy right away. No clots either . It's reddish slightly like a pale red not a bright bloodly period red. I'm confused because I thought maybe I could be. My boobs are KILLING Me my nipples omgggg 😩. I have a lot of veins. To on my chest and throughout my breast.
