As a teacher I would usually take it during the Easter holidays as a precaution. My GP suggested not to do it as a precaution, only if I felt like I actually had them.
I'm no Dr, but surely you haven't done any harm- like you say it only stops them from getting glucose form the system- totally seperate to baby stuff, yeah?.
Talk to dr or MW tomorrow and I am sure they will be able to put ur mind to rest.
