Losing my hearing??

Im only 24 & woke up yesterday morning with no hearing on left ear. The voices of people transmits as whistles & distorted sounds. Its constant ringing on that ear & it's become really uncomfortable. I haven't gone to any concerts or loud places. The only thing I can think about was my security alarm that went off twice last week. The 2nd time I was able to cover my ears but that was days before I woke up without hearing. I wasn't approved for regular insurance(only pregnancy related) so I have no idea how much my visits to the dr will cost im really upset im 3 months pregnant about to finally find out the gender & wanted to buy a crib for the baby now I have this going on & it's really freaking me out. 😢😭
