I took the tablets from days 5-9 aswell. My instructions from the dr was to DTD reqularly between days 14-24. I ended up being able to know the rough time I ovulated from the date of my period. You get your period in most cases 14days after ovulation. My first cycle was day 16 and my second was day 18. On the last cycle(in which I fell pregnant). We dtd days15-20. Every day. It worked. But our cycles can be very tricky. Hope you have some luck sorting out when you are ovulating, oh and also look out for the classic signs, cramping and increased ecwm.

All the best.

Love
