5 weeks low hcg spotting help please and reassurance , ANY ADVICE WOULD BE GREAT 😘

I am around 5 weeks my hcg at 18dpo was 77 , at 20dpo it’s 109 the nurse who rang me didn’t seem hugely worried just neutral I’m going back Monday for more bloods

I started spotting today brown Cm only light when I wipe no red blood no cramps they’ve increased my progesterone suppositories to 3 a day so 1200mg (was on 800mg)

Feeling tired and faint and have some stabbing pains in my right hand side by hip bone down, boobs are intermittently sore

Has anyone had anything like this and gone onto have a healthy pregnancy??

Please help I’m losing my mind
