大姨妈月经期助手女性健康攻略社区 is very well designed. You can record and track your body performance such as menstrual cycle, weight, temperature. This helps you to find the body change and calculate ovulation, thus is quite helpful if you want to get pregnant. You could record these things yourself but probably not in such an organized way with a clear presentation. Besides, 大姨妈月经期助手女性健康攻略社区 provides some other interesting information, such as diet choice, etc. I'm using it in conjunction with my other books and testers to conceive a baby. Fingers crossed!
