i finished the pill in oct and had my first AF 4/1/09. (68 days later)i had severe pain a few days before and then a heavy with lots of clots af. (tmi sorry) i have always had very regular cycles and concieved my 2 ds' very quickly (1st month ttc) i am currently on cd31 and have no sign of either AF or a BFP . i dont think ive ovulated this month altho ive had some darkish lines on my opks. my question relates to todays drs app. i explained all of this to her. she was very kind and has reffered me for a scan and blood tests testosterone, progesterone and thyroid function. she then gave me 3 choices.. either go for blood tests today, wait for af and then count 21 days or use opks and when a surge is detected go a week later. i am confused and wondered if any of u have advice/experience. when would you say is the best time to go for the bloodtest? thanks
