This is so confusing...

Today is 11dpiui which means only 3 more days until the blood pregnancy test on Tuesday. I have been peeing more than I have ever peed in my life, and no, I'm not drinking more either. I have had sore boobs for 2 days now and I'm completely exhausted. But is it because I'm pregnant or is it from medicince or is it in my head? I don't know. I've tried to not to think about it at all this cycle and I've done pretty well until today. Up until today, I haven't taken my basal body temperature. I haven't done the pee test for pregnancy. I haven't even read on the internet what all the signs "could" mean. I didn't want to stress myself out. So earlier today I went to my friend Melissa's baby shower and it was so sweet. There were a few times I felt myself about to get emotional and I just tried to block it out and surprisingly I was pretty successful. I'm certain no one noticed I started to get teary eyed. I got rid of it fast! After the baby shower I stopped off at a store to look at a dresser I saw on the internet that I fell in love with! I got to the store and loved it even more. I decided to go home and get Josh to take him to the store to see it himself. I was pretty excited since we've needed a dresser for a while but could never find anything we liked enough to buy and look at every day. I got Josh and convinced him to go with me and he finally agreed. By the time we got to the store I had to pee so bad my only mission was to find the bathroom. That's when it happened. I got in there unsuspecting and then that evil monster Aunt Flow showed her evil, ugly face. But only a little...just some spots. I came out of the bathroom and Josh knew immediately something was wrong. I told him and he tried to comfort me. He's such a great husband to be able to comfort me when he feels just as crushed. Anyway, we got the dresser and as soon as we got home I got on the internet to research on the internet what it could be. I did sneak a pee test which was negative. I also took my basal body temp which was still elevated. Neither bothered me since it would be too early to get a positive reading on a pee test and my basal being elevated was still a good sign which further made me think it could be implantation spotting. I am going to continue with my nightly medicine and try not to think about it. So I'm going to bed thinking positively.
