You should be ok, however i do reccomend u buy ur own drug testing kit off ebay there very cheap and test ur self in future for peace of mind. Just keep drinking water and doin the stuff u've been doin you should be fine. You also have PLENTY of time, PLUS u been sober for 37 days (which must suck lol)

I test my self regualry for fun really and i detoxed after 6 days from drinkin lots of water, sauna, excersice and cranberry juice. 6 days later i tested negative so you should 100% be fine brotha.
