Hello, Doctor! I have irregular periods, occurring every 1 to 2 months. If I have sex at 2 AM but it is not fully penetrative, and then I get my period at 8 PM on the same day, am I considered pregnant? I hope you can provide some advice. Thank you!

Hello, pharmacist! My wife is 9 weeks pregnant and is experiencing a toothache along with a swollen jaw. I'm hesitant to give her any medication because I'm concerned about its potential effects on the fetus. However, the pain is becoming unbearable for her, so I would like to seek your advice. Can pregnant women safely use Paracetamol 500 to relieve pain? Will taking Paracetamol have any impact on fetal development? What is the appropriate dosage for her? Thank you for your help.
