Cervical polyps usually come back. Sometimes, one or more of the symptoms you experience are abnormal bleeding, pain, or spotting. The cause of this is not known with certainty, but it is most likely due to the changing hormone levels in the body, or prolonged infection that has not been cured. The polyp is often removed because it is usually problem-free. The doctor should closely monitor your health to know precisely everything is normal.

Menstrual cycle can be disrupted by the higher levels of prolactin hormone that may lead to irregular periods or even missed periods. Cabergoline is administered to regulate the prolactin hormone secretion. But if you still have not regular periods even though you started taking this medicine, see a doctor again or you can take a second opinion

It's normal to receive a negative result on an hCG blood test right after the missed period. Sometimes, the test can't detect pregnancy because it's too early. Therefore, if you still experience symptoms such as nausea and breast tenderness, you can retest a week later. However, it is also important to be calm and patient. If you're still confused, getting a second opinion is a good idea.

It’s good that you’ve been taking pregnancy tests but they may not always detect pregnancy at its early stages. There could be many things that may make you feel something strange in your abdomen. The ball and beat feeling could be connected with muscles or other organs. Late or irregular periods can also be caused by many different reasons. You need to have a scan done so that you can know what is happening. 

From the information given, it is highly unlikely you are pregnant. Though, it is better to see the gynecologist for more in-depth evaluation and advise

The first thing you should do is to take a test. Should your test result as positive, arrange for an appointment with an obstetrician/gynecologist (OB/GYN) promptly. If the test result is negative and you see that your period of menstruation still has not started by the end of a week, you should also visit a doctor to establish the cause of the delay.

It could be a sign of pregnancy or could be other health factors like stress, weight fluctuations or hormone imbalances. Talk to your gynecologist to identify the root of the problem and get the best treatment.
