Really.....!!!?

Amelia
Took first round of clomid last month, took ovulation tests, I ovulated and we danced and danced some more. Took hpt Sunday it was neg took one today it was neg. Af is due in 2 days give or take a day. And now i feel crampy. How come every time i take a hpt before AF is late this happens. Af starts within 12 hours. What the heck universe, what the heck?
