eye check after baby

Don't know if this is quite the right spot to ask this but anyway...

I know my eyes have changed during pregnancy and are still different to what they were pre-conception. I still struggle to read the scores on the TV from spots in the house where I used to be able to. I want to know how long should I wait before getting them checked and my glasses changed?

My eyes have been quite bad in the past (-6.0, -4.5) and so I don't want to spend a fortune on glasses lenses if my eyes are likely to change again. I'm going to go and get a new script for contacts (I can get away with a 3mth supply and then get them checked again then) in the next week or so but I'm not sure how long I should wait before getting the glasses changed (if needed). I can't afford to change my glasses lenses if they will change again in the next few months (run out of PHI optical benefits already this year:()

I was told wait up to 6 months post birth before getting my eyes checked

Yep, i waited 6 months, although I heard 3-6 months I was just too busy (lazy) to go. My eyes went downhill dramatically, and I went from perfect vision to needing glasses (not idea what my prescription is, its around here somewhere lol).
