Should I push my exam back??

So I did awful on step 1 and was aiming for a 250+ on step 2. Im doing my second uworld pass and im at 76% right now with about 40% done (first pass was 66%).

Amboss SA - 239

Nbme 6 - 221 (5/8)

Nbme 7 - 215 (5/22),

Nbme 8 - 216 (6/6)

Uwsa1 - 234 (5/30).

My test is in about 2 weeks and i still have uwsa2 and both the old and new f120. I have no idea what to do cause i feel like my uworld blocks are getting better but i keeping tanking on nbme's. Also, i really don't want to push back my date cause i feel like ill just get burnt out. Any advice/help would be appreciative.
