Welcome to HCM. It is always better to avoid antibiotic use wherever possible during pregnancy. Ciprofloxacin is given to pregnant women with caution of keeping in mind that benefits should be far more than risks. It is avoided in lactating mothers for sure. But as you are in the start of pregnancy, try to avoid infection especially you talked about intestinalt infection. Keeping a good hygiene and balanced diet will help. Hydration is also an issue when on vacation. I hope this is all you needed an answer for. I am at your disposal if you need further assistance. Healthiest Regards! Dr. Sumaira Kousar
