¿Estoy embarazada después de faltar el período durante 7 días?

The light bleeding and vaginal itching could likely be attributed to a post-D&C infection. I would recommend you go for a gynecological examination and treatment. 

Pain in the breast while breastfeeding is very common and may be caused by lactation mastitis or milk duct blockage. It is good to see a gynecologist if pain persists, it might be a symptom of a more serious condition. Hence, I advise you to visit a gynecologist or lactation consultant for the right diagnosis and treatment.
 

The chances of getting pregnant from oral sex are quite low, but it is not ruled out. The bleeding you may have had after taking the unwanted 72 pill could, indeed, be attributed to the pill itself affecting your menstrual cycle. This can cause spotting or irregular bleeding. Such a thing is not a sign of ovulation bleeding. You can experience a late or early period as well as any of the above. The important thing is to monitor the symptoms enough and give enough time. Recall the pill can throw off your cycle. If you are concerned, be patient, and take a pregnancy test to make sure. Avoid stressing out, because stress can also be why your periods are irregular. 

Taking abortion pills can make you bleed a little but it is usual to have some bleeding. If the bleeding goes away quickly and you have only a small amount of bleeding after, it can mean that the abortion is done. Just chill out and see how you feel. If you have intense pain, fever, or heavy bleeding, go to the nearest hospital without delay. 

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.

Pregnant women should only take prevent n tablets and ferivent xt t ablets for prevention under the direction of a competently trained obstetrician. Both these tablets are rich in nutrients and vitamins that play an important role during the development of fetus. But, an overdose or misuse may result in adverse side effects. Thus, it is recommended to see a doctor in these cases for appropriate prescription and use.

I urge that any medication to terminate pregnancy should never be used without consulting a doctor. The misuse of the kit can cause discomfort and should be used only as prescribed. Missing periods after use of the kit could be a sign of some other problem. A gynecologist recommended for a full examination and clear advice on what to do next.
