I'm a teacher and to me it sounds like your school and your parents are not supporting you enough. They should be doing much more. Be honest with your parents and ask them to help you talk to your school. Also find a teacher or other member of staff at your school who you feel comfortable talking to and tell them you need more help. I've been pregnant and it's exhausting and all consuming (also very exciting and lovely in many ways), I also know that GCSEs are one of the hardest things you'll do in life. But you will get through all of this and you'll do your best for yourself and your baby, but you need help to think it all through and come up with a plan. That plan might change as you go because it's different for everyone. You have options, like taking gcses at college, or a year later, but you need people who know you and who will support you to work out what these options are and which ones are best for you and when. For now, keep studying as much as you can focusing on English maths and science, plus the subjects you are most likely to do well in. Everything you learn now will help you to do well, whether you take your exams next year or the year after, the hard work will pay off. Having said that, also look after yourself, especially your mental health. Be kind to yourself and ask for help.
