Vegan: I feel fairly certain I did NOT ovulate and am not pregnant

I was using the frer opk kit and didn't get a good line this month, however we bd'ed day 10, 12, 13, 14, 16... (usually I believe I "o" on day 13-14). I noticed what I thought was a pink tint to cm this morning, but alas nothing. I have been very regular at 26 days, but I have also peed on several sticks (frer) and gotten a stark blank bfn... i will take another test tomorrow just to confirm, but i already know the answer

Had sore BBs yesterday and I was positive af would be here today but alas she isn't!
We have been waiting and trying NOT to conceive, until this month, when we knew it would start being okay for my job. And now I think I screwed it all up with way too much nursing!! We have a three to four month window, and since ds came with no problems, I guess I just assumed this one would be fairly easy too!
I did purchase vitex today... what dosage do people have success with? I have read differing opinions... how long do we think until prolactin levels decrease? DH is doing the bedtime routine tonight... as long as I am not there, it's okay, but at nap today we had some major screaming to nurse!
