Period while pregnant

I was late on my period 4 days and i took about 6 pregnancy tests all of them being positive about two days ago and took two other ones last night. Yesterday I noticed light brownish/pinkish sporting when I wiped (TMI sorry) but this morning I woke up with heavy bleeding just like a menstrual period. What happened? Should I wait to test again? Also I am 4 weeks and 4 days
