Positive pregnancy tests but bleeding - TMI

Hi all, just wondering if anyone has come across this before or if anyone has any advice?

So all this has happened really quickly, I found out Monday night that I was pregnant. I worked out i was around 4 weeks, anyway the same night I started spotting. Tuesday morning there was a lot more spotting, I was say pinkish and I started freaking out. I called the doctor and they said they can’t do anything until I’m 6 weeks.

Since then I have been bleeding everyday. Not enough to fill a pad but the colour varies, it has gone from really light pink to brown and sometimes, only a few occasions, I would say 3, I had been bright red when I wipe.

Today (Sunday) I haven’t had anything and I’m still getting positive pregnancy tests. I would say the bleeding was too much for implantation but not nearly enough for a period. I’m super confused and don’t know what’s going on. I’m 5 weeks 2 days today so just waiting till I’m 6 weeks and still getting positive pregnancy tests and hopefully can get booked in for a scan but just wondering if anyone else has had this before? Thanks
