AIBU to switch pills midway through a pack? From Yasmin to Microlite. Started Yasmin for the first time this month (4th November) and have been having really bad migraines since. I had a three month break from any contraception and just started back this month. Is it safe to switch packs midway through? Had sex only once this month but it was a couple of days ago so a bit iffy about swapping. Don’t want to pester the GP about this. Any advice?
