Bled for 6 days with cramps and clot i thought i miscarried HCG levels from 602 to 1003 i am 6 weeks pregnant did i miscarry or is it just implantation bleeding?

It's difficult to determine definitively without further medical evaluation. A rise in HCG levels from 602 to 1003 is a positive sign and may indicate that the pregnancy is still viable. However, bleeding and cramping can occur in early pregnancy for various reasons, including implantation bleeding or a potential miscarriage. It's important to consult with a healthcare provider for an ultrasound and further assessment to understand your specific situation better.
