0.50/1.00 NL Ad6h two pair facing river min-raise

[smutgremlin]

I hate these sort of hands because this hand came right at the last orbit of my session. I had very negligible stats on villain. Is this a complete spew, and is there any way I can fold this hand?

<font color="red">Hero bets $17.50</font>, BTN calls $17.50

River: ($58.30) 7[img]/images/graemlins/heart.gif[/img] (2 Players)
<font color="red">Hero bets $35.00</font>, <font color="red">BTN raises to $70.00</font>Hero???

Should I be slowing down on the river here because of the flop and turn calls or is my bet on the river fine?

Thanks in advance.
