😪😖Help, please!

Help! I'm around 5 weeks and I had an ear infection/ bronchitis about 2 weeks ago and now I have what I think is just allergy issues... What is ok for me to take? I remember with my daughter, I couldn't take anything.... But I'm a teacher now (aka I would hate to call in sick for this) and I need some relief until I can get in to ask a dr.... HEEEELP!
