Thanks for query,
This is quite unfortunate event happened with you.
It is possible that you might get forming abscess
which is very distressing situation.
As you have got 6 months pregnancy
there is not much problem taking some safe antibiotics.
During first trimester any antibiotic or unnecessary medicine should be avoided.
So after consulting your Obst. you may take safe antibiotic like amoxicilln.
Otherwise once abscess is formed it is very distressing position.
Ok and bye.
