Stopping AF wedding day

I’m getting married to be best man ever in July..💗

AF has been to the day, bar 2 cycles in 28 months ! 😞

So fed up TTC, but the wedding planning is now keeping me occupied for sure !!

AF arrived today like clockwork and I can only see as far as June prediction… is there anyway I can predict July, or do I have to wait to next month?

If AF comes on my wedding day etc, how do I work with this??

I’ve not god a great doctor and I no longer have any contraception patches / pill.

Would be strange asking the doctor for these with TTC.. was going to ask someone in work, but didn’t want to discuss my TTC business.
