Confused, when do I start counting days as DPO?

[KC6]

Hey

This is my first month using OPKs and I got a positive yesterday and today, CDs 13 and 14. So do I start counting from tomorrow as DPO 1? I know OPKs only detect the surge of LH, so is a sign that ovulation is going to happen. When do you all start counting??

If you got positive today as well I'd say BD today and for the next two days. Also check again tomorrow. Usually women who chart can pin point there dpo. But what you can do is the day you get negative opk after positives count it as O day and then the day after O will be dpo1

It's really impossible to know for sure exactly what dpo you are unless you know exactly when you ovulated. Once you get a positive OPK, you can ovulate 12+ hours from the positive. Actually, you can get a positive opk and not ovulate at all. If you are temping and/or using temping software, you can usually confirm ovulation after a sustained temperature rise of at least 3 days. I was using fertility friend and by the time I knew for sure I ovulated, I was considered 3dpo. Hope this helps!

when you get a positive OPK, you would count the following day as the O day, then the day after that as 1 dpo.

Temping is really the best way to be sure of when, and IF, you are ovulating. Some cycles I have ovulated within 12 hrs after my first positive opk, other cycles it is later. But temping confirms that I did in fact ovulate and on which day.

Thank you!

I said I wasn't going to do it, but if I get a BFN this month, think I might start temping next month. I'm assuming i'm 9 DPO today, might start testing as of tomorrow.

OPKS are good because they give you a heads-up that you are fertile
Temping is good because it tells you that you ovulated

Separately they give you some idea of what is going on but together they give you the full picture.

Try both. You'll have all bases covered.

I'd also suggested doing vaginal temping vs mouth. It's more reliable.

Hey I'm confused with this as well! I had my first positive opk on 9.19.13 and have had positives ever since!! Idk what day I really O'd or if I even did?! I tried temping before but am OCD and will temp more than one time to be sure and always get different readings so I got frustrated with it..
