Pain and hot flashing

I finished my last pill on my last round of clomid day5-9 and I'm sitting at inlaws and all of a sudden my back/side (right side) starts paining really bad. It's like I've been sitting too long. And then my lower stomach starts hurting badly. So now both are hurting-like period pain. I'm on day 16 of my monthly. Anyone know what could be wrong? You know, other than being annoyed and ready to leave inlaws ;) I'm sitting here trying to play it off but I feel better when I'm walking around :(

Oh the hot flashing came and went during the height of the pain so I think that was just my body reacting to the pain.

i finished my last pills last night 3-7, I too have that pain. It'll feel like a really bad cramp....and I'll get hot flashes...and a really bad pain in my back, like it'll just throb.
I think there is so much going on with our bodies, the pills are changing so much that there really is no telling what the pain means..
