Beyond confused low hcg

Tenielle

So, I am so confused. I had a 5 day embryo transfer and am currently 5w 1d pregnant however my beta tests were low 1st one at 4w was only 25 then the next one was 75, I had been testing at home to see if my lines were getting lighter as I was told to expect a miscarriage however today I got a dye stealer not first morning urine and came up in less than a minute. I’m so confused and have to wait until Monday for another blood test..
