I haven't been feeling well for the past week my back has been hurting, I have more headaches than I usually do, loss my appetite, my breasts are tender, and I noitced even the areola is a little bit darker but my sister says it all in my head. I had unprotected sex about 2 weeks ago and its not time for my period... but I just have this weird feeling

Pregnancy is going to be possible anytime you have sex, in particular unprotected sex. When is your next period due? If fairly soon, it could be symptoms of that getting ready to start. You'll have to see what happens when you are due for your period or at least a few days before it. You could try at test at that time if need be.

I just got my period but I have had all these symptoms for almost 2 weeks... I don't know what to do or think

Well, if you just got your period part of it may be pms. The only way to know for sure whether you're pregnant will be to take a test though.

But the thing is I've never had any of these things before when I had my period... but I'm guna take a test
