Tylenol for Migraines & TTC/Early Pregnancy

Hi everyone. I get terrible Migraines and usually take very strong medication for them. We are TTC and I just finished ovulation, so may be pregnant (too early to tell). I had a terrible migraine last night and took 3 extra strength migraine Tylenol. I heard Tylenol was okay but is that too much? Did we just ruin our chances? Has anyone else taken multiple Tylenol and still gotten pregnant?
