Anxious - 2nd AZ vaccine on Tues

After first AZ vaccine - felt fine that day. Next morning woke , read e mails then realised I’d lost my central vision. Got up, sat on sofa with cup of tea - vision came back after 20-30 mins. Then got a migraine. Migraines not unusual for me( roughly monthly) but have never experienced loss of central vision before. Felt fine next day.
The talk of blood clots has now been in the news related to AZ vaccine so it’s made me anxious about 2nd. Tried to speak to my dr - no appts for 2 weeks. Plan is to speak to the duty dr pre next jab
Anyone else experienced visual loss problems after jab? Or pre migraine?
