Waiting. TWW. 10 DPO.

So, I took a pregnancy test 9 DPO (yesterday) and got this. It is a very very very faint line. I can only see it at certain angles. Here are pics:

After I tested, I started getting really excited because I was sure it was the start of something. Then, this morning, I got this:
Nada. Zip. zero. These are both FRER tests. Period to come 5/12 (Tuesday).
Why would I get a faint line yesterday and nothing today? It's so weird! I need 14 DPO to be here today. Haha!
Think should test again tomorrow or wait till Sunday? I know it's early. I'm just so excited!!!!!! :)
