Congratulations! 370 is actually okay for early detection, but honestly since HCG levels vary so much between people (some rise faster, some slower), the best thing is to go back in a few days for a repeat test, that's what my doctor always insists on because it's the doubling that matters more than the number itself, not the single reading. A few of us tried stressing over the actual numbers and drove ourselves nuts, but our doctors all said the same thing: if it's doubling nicely in 48-72 hours, you're golden, so check back with your clinic soon and see what they say!
