Headaches

I have had a headache since yesterday morning. I had a few while taking the Femera too. Normally I do not get headaches often (maybe once every few months). I am assuming that these headaches are a side effect of the medication. I don't want to take Advil because I am afraid of any possible interactions (maybe this is stupid) so I have been trying to tough it out but I am starting to feel like I can't think straight because my head has been hurting for so long...
