Me and my partner haven't been TTC only until recently, but we used no form of contreception all last year( just the pull out method!) my periods I think are very irregular, can range from day 28 to day 41? Has anyone else had this problem? Also I am only on for 1-3 days which is great but when I speak to other people and they have a 7 day period, kinda makes me feel abit like an alien. 😕
