(main reason for it in the long run will before a natural birth control after kids) please let me know what one you have and how do you like it! I know they are expensive but I feel that it will be more accurate then me trying to do it myself! if you use a different brand monitor let me know,what one and why u picked it! please only answer this poll if you use a fertility monitor. Thank you so much for the help!
