Those are symptoms of pregnancy, but I think its still too eairly to test. There a lots of factors that can affect periods, stress being a big one of them. I'd wait
or two, then test if you don't start. If your not looking to get pregnant right now you need to use protection next time. Birthcontrol is great, but its also not 100%. I know because I was on birthcontrol and I'm 5 mnths pregnant. Use the birth control, use the condoms, and be safe. Take care!
