Slight bleeding while 8 was pregnant. Help! TMI.

For the past week, I would go to the bathroom and when I wiped it would be a very light pink. Then a couple of days later it would happen again, then this morning I went to use the bathroom and this happened. This is the darkest it’s been. Please tell me if this is normal. This is my first pregnancy and I’m not sure if this is something to be worried about. Or if my overactive brain is messing me with again.
