I hope this works out well for you. There will be as many people who reply, "yes, I did it and it was fine" as there will be people who answer, "no, nightmare personified, don't!" because it depends on so many things - your personality, your support network, among many others.
I thought I'd answer because I also teach secondary English so there are further things to consider. English is one of the subjects, because it is skills based and the subject knowledge is almost limitless, that carries an increased workload from point of view of planning and marking and you should not underestimate that.
Also, so much depends on the placement and mentor that you get. Some are brilliant and very supportive - others less so. Or you may love your placement and click immediately but, also, it may not be the school for you which will makes things more complicated.
My own experience is that I did my PGCE year as a single parent of four - at the time they were 6, 9, 11 and 14. It was the worst year of my life. It has entered family folklore as the year that nearly broke us yet that we somehow survived - just. At one point, around Easter, the only thing that prevented me from quitting was the fear of having to pay back the childcare grant. But despite the enormous damage it did to my family and my mental well-being - I did actually do it, somehow. It proved that nearly impossible things are actually possible.
So can you do it? Yes, but don't underestimate how difficult it will be. Should you? Do you really want to? Only you can decide.
