Hcg levels

Hi all

Probably just stressing myself out but I am pregnant with my 3rd - I was actually on the pill but happened to change pills which as I thought the new pill I was on was making me bleed but looking back I’m thinking that maybe I was already pregnant 🤷🏻‍♀️ (my last bleed was 7-9th April (borwny-red) and then another one day light bleed on the 16th April..) I have no idea what has gone on and it’s stressing me out not knowing when my last period was or when I ovulated as I kept bleeding on the pill I changed to 😔 but I did have a blood test Tuesday 12th May and my hcg levels were 4085 I also took a clear blu digital and it said 3weeks plus which means can be anywhere after 5 weeks along... what was everyone else hcg around 5-6 weeks??
