Help with going back to college?

I am 21 years old and currently on Jobseekers, this september coming up im due to start a course i have just been accepted on at college 'Access to Nursing & Midwifery' as i want to become a nurse. the course is only over 2 days 9.30am-6.30pm making it 18 hours a week, my jobseekers advisor told me today it would mean id loose my benefits as its over 16 hours of education. ive tried looking online and cant seem to find much straightforward help on what i can get help with financially. i dont want to give up my place at college it wasnt an easy course to get into and i really want to make something out of my life not be stuck on jobseekers with no decent jobs out there. the only other thing i will mention as not sure if this alters any benefits i may be entitled to but i am currently 15 weeks pregnant- please no spiteful or unhelpful comments. i am doing this for my baby to ensure i have a rewarding and good paid career, to give him/her a good life. please advise/help especially if you have been in similar situation or work in benefits? stuck at the moment! x
