The nurse had a hard time to insert the cathedral into my cervix. It was bleeding and freaked me out for a bit. The first time was so easy and fast. I dont know if its a bad sign? :( also all the number of this time is not as great as the first time with only 6.8 lining and 7mil post-washed sperm. Does anyone succeed with these numbers and on the 2nd try?
