OTC Fertility Aids - Advice

My husband and I have been TTC for 2 years now with no luck.  This month when I got my BFN I kind of came to the realization that we are not going to become pregnant without some sort of outside help.  The nearest appt with my GYN wasn't until June.  So I was searching online about OTC fertility aids.  I found a couple "all natural" aids that are aupposed to be just natural herbs and vitamins, but I also seen eeer places that you could get Clomid OTC.  So I am debating on starting Clomes, but I have always heard of it being a perscription and was wandering if anyone had any advice.  Do you think it is safe to start taking on my own?  Or should I go with the all natural or just wait for anything until I get to the GYN?
