I'm finally pregnant! Hcg is 25,It's like 8 or 9dpo please reassure me

Dina

I'm ttc for 2 years. I had miscarriage in May but my husband and I have no problems concerning fertility.

This cycle I was taking letrozole (femara) CD 3 to 7, then on progesterone gel.

My LMP is 16 September

I had pink spotting on 4 October so I took a hpt on 6 and faint line appeared. Today 7 October hcg is 25 ,, is it too low? Or it's very early pregnancy as my period is not due until maybe 13 October
