Why hasn't the bleeding stopped after miscarriage?

If you had faint positive pregnancy test results and the ultrasound did not detect a pregnancy in the uterus, it's possible that the pregnancy did not progress or was very early on. So the bleeding could also be due to hormonal imbalances or other factors. Check with a gynecologist to be rest assured

Periods don't always need to be regular. Irregular periods can occur for various reasons, even after sex and ejaculation. Bleeding three days after sex could be implantation bleeding, stress, hormonal imbalances, or even pregnancy. If you are nervous, you can take a pregnancy test. To help regulate your periods, stay healthy, eat well, and manage stress.

You have a small cut on your vagina after you were intimate. This is no surprise because the skin down there is delicate. It might cause pain, redness, or a bit of bleeding. To speed up the healing process, you can keep the area clean and dry, avoid using scented products, and apply a gentle cream or ointment recommended for cuts. 

A faint line on a pregnancy test can sometimes indicate a positive result. In many pregnancy tests, even a faint line can suggest the presence of the pregnancy hormone hCG. A faint line could mean that you are in the early stages of pregnancy, as hCG levels might not be very high yet. So it's recommended to take another test after a few days to see if the line becomes clearer.

It is common to be worried about extreme thyroidization of your periods after taking emergency contraception; so, in this case, you are suffering from feeling anxious. Late periods are those that can occur due to stress, hormonal fluctuations or other changes in your body. The feeling of chest tightness and nausea could be associated with anxiety or caused by hormonal changes. You need to watch your condition closely and consider giving yourself peace of mind by using a home pregnancy test. In case if you aren't pregnant yet and symptoms get worse or your period still doesn't come, please contact a healthcare specialist. They will give you tailored advice and ensure that you have timely treatment.

A negative pregnancy test means you're likely not pregnant. Stress can delay periods. Wait and test again in 1 week. If you're still concerned, see a doctor.
