Is this normal? Had this happened to anyone and still have a healthy pregnancy?

I think I’m about 10-11 DPO I’m not quite sure.. i got my positive ovulation test super super late. I got the first response positive yesterday and clear blue this morning. Went to get a blood test done and HCG came back at 6.. supposably being 4 weeks pregnant your HCG levels can range from 5-400 or more. Has this happened to anyone and still have a healthy pregnancy?
