I think I'm getting excited here. I just POAS again...I know I'm totally obsessed..please help me LOL

. I've been feeling so emotional today and my boobs hurt and I have no appetite and my stomach doesn't feel right. I had one of those test strips that I bought off eBay left over and I thought wth, why not check again. So at first there was nothing, but after maybe 30 minutes I can see a very faint, kind of chunky line. It's hard to see, but I can tell the colour is pink rather than the white background. Do you think it's an evap line? I don't know how thick that line is supposed to be. I want to be excited but I don't want to get my hopes up either. God....that means that I have to go and get a FRER and possibly waste $20.
