I had PROTECTED SEX with my boyfriend February 21. My period is 6 days late now. My periods are always irregular, some times they come a whole month late. But ever since I missed my period my stomachs been feeling kinda woozie and and crampy. Sometimes the cramps feel like my period is about to come on but it doesn't. I'm only 15 by the way, and I have no way of buying a pregnancy test. My parents have no idea I'm sexually active & I'm really scared. I know the feeling in my stomach could be from me stressing out. But I really don't know. ),:
