Worried!

Hi ladies, I am worried sick right now! I started a bad flu yesterday and not being able to take anything really my mil suggested I take a few drops of oil of oregano. I have never taken this before and she said it is natural so I took 3 drops from the dropper. Awful tasting stuff! But after I was reading the bottle and it said not to use during pregnancy. This freaked me out so I goggled it and it said oil of oregano can cause miscarriage by inducing menstruation. Now I feel like a total ass for not reading the bottle before and am so worried I may have caused some harm :( have any of you ladies ever had experience with this? I cant call my doctor until Tuesday when he is back in :(
