I don't want to wait

I really feel like I might be pregnant. I've never felt this way before. I don't want to wait until Monday to find out, I want to know now. We've always said I wouldn't take the at-home pregnancy test early because I don't want to be disappointed when really it's just too early. But this wait! So I looked up the website for First Response, since they advertise being able to detect sooner than other tests, a full five days before your missed period. I expect my period Sunday or Monday, so I am 3-4 days from my period. Here's what it says on their website:

In clinical research, FIRST RESPONSE® Early Result Pregnancy Test detected the hormone level in 69% of women four days before their expected period (which is five days sooner than the day of their missed period), in 83% of women three days before their expected period, in 93% of women two days before their expected period, in 93% of women one day before their expected period.

Only 69% can be detected this early? That is really low. I feel like that is almost false advertising, since the test only really works well 2 days before your missed period. Plus, there is that wording difference between expected and missed period that they use in their favor.

So we wait. 4 more long days...

Last night we had a scare. My 20 pound dog walked across my stomach. She is used to climbing all over us, and normally we think it's cute. I've been trying to stop her from walking across my stomach lately, but it's hard to catch her before she is doing it. After she walked on me, I had a cramp that lasted until I went to sleep. I woke up okay this morning. K looked it up and found that being hit in the stomach only affects you after 14 weeks, so we shouldn't worry about it. But the cramp really scared me. I hope I haven't jeopardized this chance.
