Question: What in the world???

*TMI ALERT*
Ok, now that I *hopefully* helped two of you, I have a problem of my own. I was supposed to have my period June 17th. It still hasn't come, and it's now July 7th. I've given up hoping for it. But here's the thing. I took a test the 25th, and it had a very faint line that I didn't even notice until the next day when I had better lighting.I took 2 more last night and this morning, both negative. (Technically I've had 2 evap lines and 1 negative.) I'm also on bc, but I was on antibiotics for a little while. I've been having all sorts of symptoms... cravings (weird ones!), bloating, extra urination, tender nipples, growing breasts, white creamy discharge, cramps, high, soft cervix, nausea, headaches, dizziness, moodiness, insomnia, etc. Could I still be pregnant? If not, any ideas what it could be?
