Bleeding at 7 weeks? Advice

Started off pink and now a few days in it’s a little heavier and red but still only just enough to leave a tiny stain on underwear. No clots really or cramps…just that weird feeling like when your period is going to start. I spoke to my dr and had an early scan that was inconclusive and they’re redoing in 10 days. Sac was there but no yolk or pole yet, nurse said it could be too early (I think I’m more like 5 weeks) or could already have miscarried. I’m torn over what to think :( can I have this bleeding and baby still be ok? Or is it just waiting for the miscarriage to really start…..Any experience would help. Thank you
