Oxytetracycline &The FirstTrimester Of Pregnancy

Patient: Hi. I found out I was pregnant 5 days ago, and I’m now 5 weeks pregnant (this was an accident!). My problem is that I have been taking 1000mg/D of oxytetracycline for the last year to help treat my acne. I have taken this medication 3wks from the date of conception. What is the possibility of birth defects at this stage of pregnancy and is a medical abortion the best choice of action?? My husband and I do not want to wait for a 20 week scan to find out there is a significant problem…only to have to consider a more invasive termination. Any advice is greatly appreciated.

Symptoms: Pregnant
