Tylenol extra strength make you sick?

I'm 7 weeks 2 days and I haven't had morning sickness so I don't think this is morning sickness... Unless it's a big coincidence lol
I took Tylenol extra strength for some back pain I'm having and within 15 minutes I felt super neaseous it's been almost 2 hours and it hasn't gotten much better... Only helped my back for an hour or so. I did eat about an hour before I took it. I'm just curious if anyone else has this reaction to it? I've never had any problems taking any kind of medications. And I don't want to take Tylenol again if that is what's making me feel so sick.
I did talk to my Dr, I wouldn't take anything without asking🙄 but thanks for your concern:)
