Hi Bri,
I think you need to be really brave and take a test ~ you certainly seem to have a lot of the symptoms. When do you think that you might have conceived? You mentioned the blood that wasn’t a period. I’m wondering if that could have been implantation bleeding.
Do you have a school friend you can confide in and take the test with so that you don’t need to tell your boyfriend if it turns out you get a negative result or get your period in the meantime.
Good luck you x
