Crying baby

My little girl is two months and lately she cries a lot when i mean a lot she cries till her little voice goes away I do everything to calm her down and it takes awhile she wasn't like this before until she got her two month shots. I give baby Tylenol and it seems to calm her down for a bit but she continues to cry so now she likes being in the bathroom just looking around. I'm so tired she does this Every night now I been up since 1:42 am and she only slept 42 minutes and ughhhhhhh advice please.
