I’m confused🥴🥴

Summer

So my HCG level is only at 102. I should be about 4-5 weeks but I can’t imagine my levels being so low. Could this be an early sign of miscarriage or unhealthy pregnancy with my levels being so wrong or what? I’m thinking I could’ve gotten pregnant from when we BD on August 6th but I’m really worried about this. Is everything okay? Has anyone heard of them being so low?
