Hcg help

Glo

I went in early for Hcg because I was feeling strange. I didn’t go thru my normal Iui cycle because i went out of town. My Hcg on 5/7 was 35.5 went in 2 days later it dropped to 9. Went in 2 days later it went back up to 38.8. I was suppose to be 3weeks during my first draw and my period is late by a day so this week 4 weeks.
