Hi and welcome to MM Willsmam
I'm sure it's not a problem this once - there may be some absorption issues but I certainly wouldn't worry about this.
It is a good idea to read the instructions so you know how to use things and what to expect. Don't take too much notice of the warnings and side effects - these things can seem really alarming - if you read the leaflet that comes with anything, say Paracetamol, one would be really scared to take them.
Do expect some reactions in the first 2-3 months - hopefully meno symptoms will improve relatively quickly but it can take some time for the body to adjust and settle. Just look forward to feeling better within the next few weeks. Keep us posted. Dg x
