Scared! Month and a half late!

Just want some advice really recently split up with my boyfriend that I was with for 2 years and a few months ago I came off the pill due to mood swings now when I came off I came on twice within the first month and now I was due to come on last month and I haven't I'm now a month and a half late nearly every morning I wake up feeling sick, I also have been getting bad stomach cramps and my boobs have been very sore for a while now I messaged my ex explaining this and he doesn't even seem bothered or interested but I'm too scared to even do a test as I've not even told anyone about this apart from him I've just been hoping that these symptoms fade away now my boobs aren't as sore but I'm still feeling sick and one minute I'm hungry and next minute I'm back to feeling sick. Just not sure what to do to be honest any advice??
