So, we want to try really hard this month

I am on CD9, and I don't temp or opk. I do have very normal 28 day cycles. So, I was going under the assumption that I will O around the 14th. But, couldn't it be a few days before or after??? We have been bding everyday (twice today

tmi sorry) I want to make sure that you can't bd too much. Have any of you read about that anywhere? It seems like I may have, but can't find anything. Also, the midwife said to bd every other day...so it didn't become a chore. Well, a chore it is not

so I just want to make sure it isn't hurting chances. Thanks for any input.
