Miscarried just over a month a go

Julia

I miscarried on the 14th January at 12 weeks pregnant, it’s been just over a month since the miscarriage and still no period. I have had some pregnancy related symptoms the same as before ie sore during sex in certain positions, decreased appetite, intolerance to some foods, a tiny bit of blood in my discharge last week and increased discharge. Do you think it’s too soon to take a test and also when have people fallen after a miscarriage. I thought my periods would of returned at 4 weeks as I was quite regular pre pregnancy. I don’t want to set myself up for disappointment of a negative test.
