FTM - Help!

On Monday 9/17 my doctor did a check and found I was 2cm dialated. When she pulled her glove out there was blood on it. She said that was a pretty good sign that labor was close. She said to expect some blood in my discharge for a few days but not to worry unless it was red. So from Monday - Wednesday I had lots of bloody discharge. On Wednesday I thought I must have lost my mucus plug because I had about a quarter size chunk of bloody mucus and continued to have small amounts that whole day. Then on Thursday and Friday absolutely no blood and no mucus. I woke up early Saturday morning and had some more bloody mucus, then all day Saturday it continued. So I thought maybe it was just the rest of it. Fast forward to this morning (Sunday) and I wipe and have a chunk almost as big as my hand! It scared me a little. The blood was still brown, like it's been but also kind of pinkish when I wiped. I'm confused and was hoping maybe you ladies could help me out with your own stories or information! I'm almost 38 weeks. Thanks in advance! ❤
