Just need answers

So I just had a 4 day "period." If it was my period, it was right on time. But it was just weird. The first day was normal flow. Then the next three days it almost looked like clear cm does (stretchy and kinda shiney), except it was red. It didn't look like normal blood. Now today I'm having a little bit of brown discharge when I wipe.

I've also been super nauseous at night and I've been constantly having vomit burps (tmi sorry). And I've been sleeping ridiculous amounts of time (10-12 hours and having super vivid dreams). Plus naps during the day! What's wrong with me? Could I possibly be pregnant?
