Yes me! i just found this thread i have always used withdrawal method around O time i have never had a slip up except when i was 23 and my then husband came home drunk and didnt bother which resulted in me getting pregnant and my now ex husband.

I dont ever get ewcm so that is no good for the billings method i can always feel when i O and it is always between day 10 and 13 which we are careful around that time.
I just had a baby so we are waiting to see how my cycles go before we know when to be careful but to be honest i am a little older now and it took ivf to concieve our 2nd daughter after losing our naturally concieved in 5 cycles 1st daughter i was always a rabbit and fell easy but now i am not so sure but dont want anymore bubs just yet if at all.
