It's supposed to go high for ovulation so that's a good sign! There's a hole in you cervix, it should either be tightly closed or open enough for you to fit the tip of your finger in it. When it's high and open that's when o is approaching, mines been high and open for ages tho so it don't mean anything, it will change once you have o'd! My cycles were normal, don't know what they will be like after the d&c though they might be wacky for a bit
