I find that I don't really have fertile CM. I never see it on my underwear so do some of you insert a finger and check it that way in case you just don't have a lot? I have a 7 year old boy and am just so afraid of secondary infertility. I haven't been on birth control in 3 years but I did have a chemical pregnancy about 2 years ago. I'm almost 28 and ready for baby number 2. Any insight ladies?
