Weird spot on flop

[Zaghomat]

CO is 35/18/2, kinda donkish preflop, but ok postflop, no major spewing.
BB is a donk and MP3 is a standart TAG

I have no idea what to do in this situation. a minraise into a bet and 2 callers looks really strong to me. At best I'm again a combo draw and at worst again higher set, made straight.

Pushing is tempting, but I dont think i have a good equity when I'm called.
