Ladies, I only have one hpt left in my stash (a strategy to keep from wasting a lot of money on them) and I think it's time to use it!

I am terrified though, we've been ttc number 1 for 19 mos and I've been disappointed so many times.

AF was due Tuesday. I usually have sore breasts and a day or two of spotting before her arrival, which have not come. Instead I've been EXHAUSTED (I fell asleep at work sitting up) and I've been nauseous. I had a nosebleed last week, which I don't think I've ever had before, and (TMI warning) I've been constipated and when I'm not constipated I've had diarrhea. I'm having constant heartburn even when I just eat cereal. And I feel like I can smell weird things. Like I know an improved sense of smell is a symptom, but I always thought it would be food or perfume smells i would notice.... Instead I can smell hot aluminum cans and my new tote bag smells mildew-y?! I feel weird!

I did fall last week and sprain my ankle pretty badly. I can't imagine that would make me late? I have been susceptible to stress in the past...

So? Is it time to use the last test? Help me ladies, I'm so scared to be disappointed again!
