I’m on my first cycle of Clomid. I have PCOS and don’t ovulate on my own. Started testing CD11 with OPKs. Thought I got a positive on CD17, but tried the CB Advanced and it was low. I kept testing and received the high reading on the digital two days ago on CD20. Is it too late to ovulate? I’m so confused. My boobs have been swollen, I’m eating everything in sight, terrible headaches and I’ve slept almost all day for the past two days. Just need some insight! Hoping I’m going to ovulate.
