Hi i want to ask some info. I am using calendar method eversince like 5yrs now and i always track my safe and unsafe days. Aside from that i have make sure that on the unsafe days my bf and i are using condoms to make sure.i let him not to use one on the 4th day before my next period will start.according to my cycle and the tracker.but now im a week late.maybe i am pregnant.i am experiencing back pain and abdominal cramps.
I have read other answer there is really no safe and unsafe days because it depends so i guess that answers my question its just that maybe a tip from others who uses calendar method to not use it.because we really cannot know when or how our body works.
