Stick interpretations

So yesterday was 12dpo and we tested. I left the stick on the bench in the bathroom, went back to bed and made Scout go and check on it 5 minutes later. She was in there for awhile before she finally called out asking me to come into the bathroom. I found her looking back and forth between the stick in one hand and the product info sheet in the other. On the stick there was a faint line in the test box. Scout was clearly concerned by the lack of a defined line but my head was saying YAY! It's a line! To me it didn't matter that it was faint, it was still positive. But Scout didn't want to get too excited by something so faint so we agreed to wait another day and test again with the hope of something more convincing. All day I had light cramps on and off. We went shopping and even stopped at BabyCo for fun but we left pretty quickly as I felt a bit ridiculous being in there when we didn't even know if we're pregnant yet. At the end of the day I was shattered and collapsed in bed. My nose was blocked and I had a stomping headache which I assume was from not drinking enough all day.

This morning my temp was high and I was excited to POAS. My urine was really light in colour but I tested anyway and the result ... a B.F.N. Talk about disappointing! The faint line yesterday must have been the tail end of the Pregnyl leaving my system. I'm feeling a bit bummed now and a bit silly for letting that faint line trick me into believing I could be pregnant. I am tired and cranky and crampy but I'm not pregnant. Clearly I must be premenstrual. I have peed (in the bowl, not on a stick) 4 times in the last 4 hours and each time it's light in colour and large in volume. I really haven't drunk all that much lately and I don't normally pee this much either. My period is due tomorrow but instead of my temp dropping, it's risen. My chart looks great. So I have no idea what my body is up to but it's annoying and I'm unimpressed. I had the flu shot on Wednesday so my guess is I'm getting unwell from that. I don't really want to give up on this cycle just yet, but I'm preparing myself for the fact that AF is more than likely on it's way. Our FS has already told us she thinks we will end up needing to do IVF so we won't be wasting our time on another IUI. We will just need to tighten our belts and scrap together the moola to make it happen.
