Hi, I'm 21 and I usually have a weird menstrual cycle. I usually get my period twice a month. But in December it only came once. I got my period Dec 30th and it was late( I assume because I didn't have my usual 2) I had what I thought was a normal period but after my period week I still had brown spotting heavy enough that I had to wear a tampon. It's Jan 15th now and I still have the brown spotting. Could I be pregnant? I'm not on BC, and I am sexually active. I normally use condoms but on New Years since I had my period I did not use a condom. Any feedback would be greatly appreciated! Thank you!
