need advice for job switching..

ShiAnna • #1 May 2017 & Rainbow baby on the way! 🌈
I currently work at a hotel front desk making a crap min wage of $8.05..I don't have a set schedule & my hours are always changing.  I just got out of training but the opportunity for me to use my medical certifications has came up & I am looking at a phlebotomist job making atleast $10 an hour. My downfall is the clinic needs to hire someone ASAP. They offer 730am-4 pm shifts Monday thru Friday as well as holidays off. Having a baby, that sounds more pleasent to me. Now if I get offered the job should I still put my two weeks in at my current job or just quit because I need a better job?
