Hi, thanks for the question
Abnormal bleeding and abdominal pain
may be due to many causes, if you are in doubt that you may be pregnant then you can do a simple urine test to confirm.For that go to a medical shop get one pregnancy
test kit, take a first morning sample of urine and do a dip strip method,i.e follow instructions as given in that manual which you have got with the kit. You will get results within 3-5 minutes. This test is 96% sensitive.
Hope my answer will help you, take care
