Can I apply for an extension of stay based on marriage in Thailand with only 6 weeks of required funds?

Hi. I wanted to apply for an extension of stay based on marriage in Jomtien. I had a problem with a money transfer and because of that I will have only had 400K in the bank for about 6 weeks before I apply and not 2 months. Will this automatically mean I cannot apply? I do transfer in excess of 100k per month into my Bangkok bank account every month, don't know if that will help.

I usually use a non O from London hence the ignorance. Thanks.
