I am going to labour in the early November, should I buy one tin of FM just in case I have not enough BM? What if I am having fever during BFing, can I BF my LO?

you can BF your LO even though you are unwell :) your antibodies will be transferred to your LO via BF and that improves his immunity. Don't worry about the lack of BM. Four in five moms have sufficient BM for their children. BM supply takes about 4-6 weeks to build up. First few days Post partum, you will experience engorgement (that's all the goodness inside you). Make sure you get proper help from a Lactation consultant on latching and how you hold your baby before you are discharged.
