3 days ago I noticed a sore swelling in the crease of my leg, between my outer labia and thingh, right where my knickers sit, I left it alone, hoping it would just go away, yesterday it was bigger, painful and obviously pus/fluid filled, this morning I am in tears trying to walk, its HUGE, so painful and I cant sit, stand, lay anywhere without there being pressure on it.

I'm thinking of going to the gp to see what they can do about it, but I probably wont be able to see anyone for a day or two, should I

a) just ring the gp and bear it until I get seen
b) ring the womens/maternity clinic, see if they have any suggestions..
c) go to emergency? (not really keen on this, waiting around in pain, not really an emergency etc.. but this what we did when DF had one years ago in his butt crack...)

just not sure on best plan of action being pregnant and all and scared of infection and in so much pain...
help please..
