I think there are a lot of factors to consider.
Firstly, do you want to spend some time with your baby after delivery other than the 4 mths maternity leave, what kind of job/industry are you keen on joining, Cos a regular 9-6pm job will leave you minimal tme as by the time you raech home after work, you are tired already and if you are gonna ook after your baby in the night, you will also be tired at work. For a regular company, they may not want to employ you and chances will be better after delivery.
Whereas if you are keen on joining the sales industry, sg. real estate, insurance, Your pay is determined by how hard you work so the company will not be concered whether you are pregnant or not. And you will have the choice of when or not to work.
This is just my personal opinion, hope it helps.
