Which week?

Nancy
<a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> says its 35 weeks 2 days, does it mean 35 or 36 week going? Also they say babies are full term after 37 or if 37 week is going on? Sorry for asking dumb question, but am just counting days. Its so hard with gd and medication. I hope it end wells and i want to be strong both mentally n physically as i dont have much hopes from my husband to give me enough emotional strength due to his nature and having cold at this time.  Least thing you would want. :(
