The antibiotic you have been prescribed is used with caution in pregnancy
though there are no studies or reports of fetal malformations. Sporlac
used to wash out unhealthy intestinal flora during infections. It is something like what we find in yogurt and it is harmless. As for your pessary, do not use the applicator to insert it. Ask your doctor if a single dose pessary would suffice. You can use papers to test for leakage in case of doubt, by checking pH. I hope I have clarified your doubts enough. Please consult your doctor for further advice. Take care.
