Accidental aspirin - 19 weeks

Ru
Hi, I'm just looking for a bit of reassurance from other mums / doctors...On a flight back from Germany I accidentally took 1x 500mg aspirin tablet (thinking it was paracetamol). I couldn't believe it when I realised, I've been so so careful even very rarely taking paracetamol and so upset I may have put my baby at risk. The midwife just said they don't advise it but thinks taking 1 won't have done any harm. I'm 19 weeks and googling it is making me terrified. ☹️ can anyone offer reassurance? X
