Next virgin Mary

Jane
I'm a week late on my period which never happens. I've been MAX a week late but then get it on that 7th day. It still hasn't come. I'm a virgin and haven't even been touched for 2 years now lol so there's 0 chance of me being pregnant
i've also been sick for a month with cold / sinusitis symptoms. and have had a throbbing headache for 2 days straight that 800mg of ibuprofen isn't helping.... should i go to the doctors?
