Is this normal? 3wk 6 days

I tested Wednesday and had three positive tests will post pic, and tested this morning just to check still positive, I have been constipated and this morning took some lactulose, later had bm but on wiping had very pale pink discharge from the front end. I am panicking now, am I about to have my period which would be due tomorrow or was this from slight straining on going to the loo? Has anybody had this? I don’t have pains or anything but worried sick now.
