Quoting ~Bethany ~3-29-12:" awe yeah and I started my period today finally so sinve I ovulate on CD 18 or 19 what cycle day would ... [snip!] ... cycle day would I get my period? And can you by feterlity blend in stores or online or does the doctor have to prescribe it?"
No you can buy it at any vitamin store like GNC. You really can't go buy when you ovulated because I ovulate at different times a each month. My luteal phase is only 10 days. Not all women have the same luteal phase. It would all depend on your luteal phase. The luteal phase is the days following ovulation. If you go by your first positive ovulation test, if you ovulated at that time then count from that day til today. That will give you the amount of days which is your luteal phase. You could have possibly caught the egg and had a chemical too since you had that positive opk when it was almost time for your period. So since you started today mark the calendar as CD1 then keep going until you get your positive opk. Mark that day on the calendar as well. Then keep counting the CD until your next period. That will give you the length of your cycle.
