I took Clomid 50 mg on days 5-9 of this month. I ovulated on day 11. Today is day 17 and I am having dull cramp - like pains. It almost feels like my insides are sore in my pelvic region. I don't have any spotting or bleeding. Could it be implantation pains?

It is possible for you to feel implantation pain. Especially since you have had a hormone boost. I don't have much experience in this area and I'm bumping this back up to the top so that someone who knows more about it can answer you.

I however believe I have felt implantation pain with my twins. Not saying that my experience is the same as yours, but I just wanted you to know that it is possible.
