Low HCG (7) at 8dp6dt

Looking for words of encouragement ..

Did my second FET 6/2 with a day 6 5cc, got a faint line (FRER) on 6/7 and then a positive digital (two different brands of tests) on 6/9 and 6/10.

However, at my beta this morning (6/10) my hcg was only 7. Clinic said the number is obviously very low but we won’t know more until the next hcg in 48hrs
