Tylenol is called paracetemol in most of the world.
This is an excerpt from Wikipiedia as I found it would be easiest to copy/paste here.
"In contrast to aspirin, paracetamol is not an antithrombotic, and thus may be used in patients where coagulation is a concern, and it does not cause gastric irritation.[28] However, paracetamol does not help reduce inflammation, while aspirin does.[31] Compared to ibuprofen—whose side effects may include diarrhea, vomiting and abdominal pain—paracetamol has fewer adverse gastrointestinal effects.[32]
Paracetamol is generally believed to be safe for use in pregnancy[33] as it does not affect the closure of the fetal ductus arteriosus as NSAIDs can.[34]"
Translation: Tylenol is not aspirin and is generally safer than Ibuprophen when used during pregnancy.
Always consult your pre-natal/ ante-natal healthcare provider before taking any over the counter drugs.
