First off I am 16 and my bf and I had unprotected sex about the end of May.(he is now my ex.) I had a regular period in June, and in July it was 6 days late, and this time it did not come at all. I did one of those home made tests, the dandelion leaf test and it had a few red blisters after 30 minutes after i peed on it. as the site I read, said it would mean you are pregnant if it got red blisters Is this true? and Could I be pregnant? I've been feeling a little odd like, morning sickness, headache, backache and such. Please reply quickly, and that you for your help.
