Anyone have any insight?

So my period was supposed to start 6 days ago and hasn’t . I took a pregnancy test when I was 1 day late and it was negative. (Although my husband said he saw a super faint line) I told myself I would wait until Friday to take another test to allow my hcg levels to build up if I really am pregnant, or didn’t get my period by then. In the middle of the night I woke up with what would feel like my normal period cramps and some light bleeding. Nothing like my normal bleeding when I am on my period, and now it has stopped. Should I still plan to test on friday? We were so excited as we’ve been trying for 6-7 months now. Anyone have anything similar?

I should maybe also mention I’ve been using glow for a couple years now and my period has always started on the day it said or I would show signs it’s coming and get it the next day.
