Actually, it's lack of CM after HSG. Completely dry as a matter of fact. I had a HSG last Tues. (cycle day 9). My cycle is regular (28 days) and I usually have EWCM on days 14-15 and I actually feel ov. pain. I was really crampy the next two days so I really wasn't paying much attention to CM. But, I think I saw some EWCM on cycle day 11. We have BD on days 12-14. Also we have been trying for 8 mo. now. Any insight???
