can somebody pleasee answer,i’m soo nervouse

Hey girls.So on 17th i was at the gyno and she told me that i was all right and everything is normal.My period was expected on 18th but i’m late with 8 days now.I always have sex with a condom+my boyfriend pulls out when he cums(even though we use a condom)+we always check the condom with water and i don’t have sex on my ovulation day.I took two tests and both were negative but my period still doesn’t come.Should i be worried?I should mention that i took medication(paracetamol) 3 times a day for a week,because i was sick.Could it be from that.And also it was my first time at the gyno and i was super stressed and anxious one week before the appointment.
