Studying in third trimester/during maternity leave

Hi all, I will have to complete my Masters along the pregnancy and I am aware it’s gonna be tough since I am also working part-time….. I am thinking of either taking : 1) 2 modules in the third trimester, 2 electives during maternity leave or 2) 1 module in the third trimester, 1 module + 2 electives during maternity leave I’ve been debating in my head and cannot come to a decision. Any mums / fresh mums with any advice? I’m currently in my second trimester with my first child so…..I have insufficient experience as you can tell……so advice on the above options with be helpful!
