Is this normal after taking letorzole?

Jennifer

I took letorzole 2.5 cycle day 3 through 7. I am now on cycle day 10 and my stomach is so tender. I feel like AF is about to start. Is it normal to feel this way? This is my second round but I was told last cycle my body didn't respond the way she wanted it to. I didn't feel like this at all last cycle. I have taken ovulation tests and all are negative. This is very new and I'm not sure if I should worry or not.
