If it was 2 weeks after the start of your cycle is possible, and I hate to say, likely, but I don't know your cycle so I can't say for sure. I've ovulated as late as day 18 before, and my normal is anywhere from day 13 to 16.
Keep this in mind: even if you time it right, you only have about a 25% chance of getting pregnant in any cycle. I don't know how old you are, but the older you are the lower your chances.
Now if this all happened a week ago and there was a conception implantation would be happening about now. You may consider the Vit C and eating a lot of acidic foods to make your body less hospitable to implantation. Combine that with the meditation (I think the "thanks, but no thanks" meditation shows respect for what may be going on in your body at the same time asking for another option) and perhaps visit a sympathetic accupuncturist who will know what to do to bring on a period.

[Personal cosmology to follow. Take it or leave it at your will:
] I know you're conflicted and anxious. Look deep inside to see what it is you really want and then follow through on the options available to you.

Again, my personal philosophy, leave it behind if it's not helpful to you.
Sending you hugs and wishes for a peaceful outcome.
