12 week gap parental pay

Hello, I have a questions regarding the 12 week gap for parental leave work test. Is the 12 week gap continuous or is it 12 weeks in total for the 13 month work test? Examples I am casual and self employed. - I had 4 weeks unpaid with both jobs due to nursing placement - I had 3 weeks off over Christmas/new year because there was no work for both jobs - I will go on maternity leave 2 weeks prior to my due date unpaid That is a total of 9 weeks unpaid but it’s not all in the one hit. Doesn’t leave me much room for movement if I am unwell ect. But if it’s continuous 12 week gap then that doesn’t apply. Any advice will be helpful, thank you 🤍
