Early pregnancy test

I made a hcg test 5 days before my period and it was positive ( my last period was 1 of march and it is irregular but my last periods last in average 31 days and ovulation is happened at day 18 or 19)
I made 2 blood tests one 4 days before expected period and the day after they were 23.8 and 36. There is no bleeding or bad cramps
Is that normal and indicates healthy pregnancy or the numbers are low?
