Aww Kirsty *hugs*. It can be really frustrating can't it! I too read that clomid can cause higher temps and pregnancy-like symptoms for some people. Unfortunately I don't think it's possible to tell if those things are due to the clomid or a pg until after you find out whether or not you are in fact pg.

My temps were always fairly erratic anyway, so I couldn't really tell if the clomid had any effect on them, but I think it's probably something that would vary from person to person. If you have a look in the 'Charting Your Cycle' forum you'll find a link to my pg chart in the successful conceptions sticky thread if you're interested in having a look.

It is sometimes possible to have a dip in temp in the middle of your LP without being pg, even if you're not on clomid. I've read that it's due to a hormone surge (can't remember which one at this point in time) but you don't necessarily have to be pg to get it. However that said, it can be a really good pg sign. I had a temp dip then a rise at 5DPO with this pg.

I'm sure all of the not knowing is driving you absolutely crazy! When do you think you will test? Sending you lots of luck and BFP vibes!
