When to test?

Christina
I'm freaking out! I have to talk to someone that won't spill the beans to anyone. I was supposed to get my period yesterday and haven't gotten it. I know my period is irregular so I could still potentially get it. I got cramps on Monday but haven't had anything since. I don't want to get my hopes up, but I'm hoping I'm pregnant. However I haven't really gotten any pregnancy symptoms. I'm think of waiting until Monday (I would be 6 weeks pregnant if I am) to test....just in case I still get my period this weekend. I don't want to buy a test and then it being a negative....but I'm freaking out and want to know now. Anyone else in the same boat?
