How many DPO am I?

ACSK510 · January 2011

So I got my first +OPT on Thursday the 20th, Cylce day 15. I continued to get + OPT until Friday evening. I took one Saturday and it was still a faint test line. But not anything like the others, not as dark as the control line. So do I go by the first positive OPT test? So my fist DPO would be Friday. So am I 4DPO?

First month using OPT, and I do not temp. Sorry

Can't really say then. Sorry.

Are you charting? A + OPK just shows that you have an LH surge, it doesn't necessary confirm ovulation.

ETA: Just saw that you're not temping. Sorry, you can't really know without temping.

jchanth is right, you can't really know for sure unless you temp as well and get a confirmed temp shift after the fact. in saying this, some people can have a long LH build up that is strong enough to give you a few positives in a row. usually if you're just using OPK testing alone, you would assume that it is the last really positive OPK that is the one you should go by, you possibly O'd one or two days after that. But again.. without a confirmed temp shift it's impossible to know for sure.

I'd recommend temping next cycle if you don't get a BFP this time round.

GL!
