Hcg value

I really need to get this out of my mind. I had my baby on 29th May 2018. My periods returned in July and I had period occuring twice for a couple of months. Then my cycle length increased. I had 11 cycles after delivery. And it ranged from 22 days to 54 days. My last cycle was only 26 days and it was way lighter too and lasted only 2 days. I got pregnant this cycle. The pregnancy was not planned and I am still breastfeeding my baby. I usually go without periods for more than 20 days now but I tested this time only because of fatigue. I did an hpt on cycle day 39 and I got an instant positive and the test line was much darker than control line. Next day that is on cycle day 40 I had a beta hcg test done. My level was 33550. 11 days later on cycle day 51 I had my first ultrasound and I measured 8 weeks pregnant. I am scared about this hcg value. Does this come under normal value?
