Very confused

Maria • I

My ultrasound seems I am ovulation but the opk was negative always, I got an injection 1 day before <a href="https://glowing.com/glow-fertility-program">IUI</a> to may sure I ovulate and 1 day after <a href="https://glowing.com/glow-fertility-program">IUI</a> had a lot of cramps so I am confused whether I ovulate or not maybe I just waisted the money on <a href="https://glowing.com/glow-fertility-program">IUI</a> but nothing will happen this month
