I have pretty irregular periods. But this is the first time that it is 2 weeks late. I don't use birth control and while my boyfriend and me do fool around, we never actually have sex. The most he's done is grind against me or rub his tip against my clit (and he never comes on or in me). The last and only time he did that this past cycle was the day my period was due. So I highly doubt I'm pregnant. But all of a sudden I get cramps and lower back pain. I've even been having trouble sleeping. I've googled some of these symptoms just to make sure I don't have some infection or anything. But everything on the internet is pointing to symptoms of pregnancy. I do stress out a lot and actually had a medical emergency before I was due. That definitely put some extra physical stress on my body. If someone could reaasure me that I'm not in fact pregnant and that this is normal? It worries me that I'm this late yet am having a lot of the symptoms as if I had started my TOM.

Help?
