I cant stand the thought of putting anymore synthetic hormones in my body. I have been tracking my cycles on mymonthlycycles.com and avoiding sex or using a condom during my fertile times. I actually extend my fertile time just to be extra safe ! I consider myself fertile from the day my period ends until day 20 of my cycle. I run a 26-28 days cycle so I do ovulate mid-point. I still make my DH pull out even when I am not fertile.
I also can not use latex so I use the Avanti condoms made by Durex. They are made from polyurethane. I have been using this method for 18 months and so far its been working !
I should say that I used condoms everytime we had sex until until my cycles were back to normal after removal (about 3 cycles).
Pills effect everyone differently. My BFF is on Yasmin and loves it.
