I have woken up today with tonsillitis, just had it confirmed at the Doctors and he prescribed me Phenoxymethylpenicillin which I think is just the same as Penicilin(?). I told him I was 5.5 weeks pregnant and he assured me that it was considered safe to take in pregnancy and that he felt the safest thing to do is to treat the infection. He gave me lots of reassurance about how itd been around for years, women in 'third world' countries had healthy babies despite horrendous illnesses etc. He was really sympathetic.
However I was also pregnant last month and had tonsillitis for which I was given the same antibiotic before I knew I was defintely pregnant. I lost that pregnancy at about the point I am at now. I am absolutely terrified it will happen again.
After seeing the doctor though I decided it would be best to treat the illness because last time I didnt see a doctor for a few days and it had got very bad with fever etc before I got antiobiotics. However I have just double checked on the nhs website and it says that penicillins are generally considered safe during pregnancy but that the safety of phenoxymethylpenicilin hasnt been proven and it shouldnt be taken unless clearly needed. So now I don't know what to do...i had already taken one tablet 
Anyone have any advice or experience?
