10 weeks, miscarriage?

So I’m almost 10 weeks pregnant. The last two weeks I’ve had energy and just feel very ‘normal’, before this I was puking and incredibly tired. I thought this was odd so I started to take pregnancy tests to see if they were lighter, which they are. I was wondering if this would for sure mean miscarriage? And if so, since I didn’t bleed or have anything like that, would I need to do a D&C? My first miscarriage was earlier on and I bled, but have had nothing with this one.
