Hello, when we had covid my boyfriend had the most awful cough. He was in the toilet bringing up mucus about once an hour and it sounded like he was coughing all his organs up. It was horrible! They thought he might have an infection so were going to prescribe him antibiotics but didn't in the end. It sounds like you're ok from your other symptoms but speak to the dr if you need to. My boyfriend was very ill but he is completely fine now and I'm sure you will be too!
