This cant be,could it?

I just got off my period 9 days ago which was 28 days late. My period lasted 6 days.

I have been sick since last Tuesday with a horrible cough and chest pain so went to the hospital today. They gave me the drink that numbs your throat and a breathing treatment and, of course, lots of meds to take home.

Well I get home and go to the bathroom and wipe and I'm spotting which was odd so instantly I take a pregnancy test and

Could this be real?

We had sex before my period started way late and again 3 days ago
