Contact the British Pregnancy Advisory Service Tel 03457 30 40 30 (I'm not sure of the times they are open)
I believe you can terminate up to 23 weeks and a few days, but do see your GP and/or take pregnancy advice.
If you still decide to end the pregnancy they can tell you how to access counselling and how to cope emotionally with the after effects of the pregnancy loss. Counselling is just to make sure you have thought everything through first and still want to terminate, and as support for you afterwards. Don't let anyone influence your decision - this is your decision alone and it is your body undertaking the risks by carrying any foetus if you keep the pregnancy going.
If you change your mind and decide to keep the pregnancy Uni could still be an option for you, but have a good think about what you want to do? You have nine months to still just keep going virtually as normal with lectures, assignments etc In the three to six months after the birth baby is not very mobile, just needing feeds, fuss and changing nappies. It is difficult logistically but still achievable. You would need to contact your Uni welfare services to ask what support facilities they offer for single Mum's. Finance is more difficult, but if you are still doing your course you would still be entitled to your student loan.
What ever you decide will be right for you, and you don't need to justify it to anyone. Good luck, there will be so many women in the same situation and unfortunately there is not such a thing as 'a little bit pregnant' and the overload in thinking is sometimes overwhelming.
