SLady, if it was me, I'd take it and crack on with clomid. I guess for me I'd look at it like this, no one is going to write down that they had a lovely dreamy experience, everyone is quick to write the negative, in any given situation. I'm 8 weeks pregnant and have had no sickness or nausea at all, but people who do are super quick to write down how bad they feel, but how often do we hear of women saying, yup, I had the best 12 weeks ever, didn't feel ill, nothing. It makes others worry that something is wrong or that they will feel so bad too, which isn't always the case.
What I'm trying to say is, you won't know how you'll react to it. You might feel right as rain, normal period, boom. Or you might feel crap and it could be heavy and horrible but googling won't be able to tell you about you! If it is bad, it's a week of your life and then it's done? It won't last forever.
I also wouldn't wana put off taking clomid any longer. What if AF never comes naturally? Then you'll regret all that time that you waited in hope that it would come of its own accord.
Good luck and we're all here to support you, whatever you decide!
