Antibiotics and pregnancy

[KimmyF]

Hi All
quick question has anyone ever taken antibiotics whilst pregnant?

I have a very large and painful sebatious (sp) cyst on the back of my next, painful to the point of not sleeping and difficulty turning my head. it is about the size of a ten cent piece. Anyway it has been causing me pain for two weeks and gotten worse so i went to doctor today and she said it is infected and they cant remove it whilst it is infected as the local anaesethic wont work so she prescribed me Kelfex antibiotics to clear up the infection. she assures me they are safe in pregnancy ( i am 11 weeks) but i am nervous, i have got the script filled but am a bit scared to take them but know that i have to to make the infection go away.
Anyone else had to take them in pregnancy before?
Thanks in advance
Kimmy
