Hello and wleocme to HCM
Periods are all together absent in case of pregnancy
If in doubt pregnancy test will tell about the pregnancy status.
If blood is present in urine, a urine test must be taken after consulting your doctor.. If the blood is present in urine further investigations will be undertaken to find out the cause of blood in urine.
In case your periods are irregular, you can visit your gynaecologist for further work up.
Thanks and take care
