Irregular periods, weight gain, constipation and itchiness may indicate a medical condition. One should seek the help of a gynecologist in cases where periods are not on regularity and that of a gastroenterologist when one is having constipation. A dermatologist should be consulted for weight gain and an endocrinologist, on the other hand, in case of itchiness. Do not dismiss these symptoms as a failure to diagnose and treat correctly may diminish your physical health and happiness.

Vaginal itching is a symptom that can be due to a number of causes, such as yeast infections, bacterial vaginosis and STIs. It is necessary to go to a gynecologist for a correct diagnosis and treatment. 
 

Pinworms are tiny worms that infect the intestines and can sometimes spread to the vaginal area. They cause itching and redness. Medication can eliminate them, but it's important to wash bedding and clothes frequently to prevent the infection from spreading. Always remember to wash your hands before eating.

Noticing brown blood clots in your urine during pregnancy can be worrying. It might be a sign of a threatened miscarriage, which can cause bleeding and clots. It's good that the bleeding has stopped, but please stay alert and talk to your obstetrician to discuss your condition and get the right treatment. 

The effectiveness of the pill depends on factors like timing and individual variables. If you're sexually active and concerned about pregnancy, consider taking a pregnancy test if your period is significantly delayed. 

Failing to show up for the period is a little terrifying, but let's work it together. The causes of these symptoms could be psychological, hormonal, or reproductive. As far as you are concerned, you also had sex without protection; therefore, the likelihood of pregnancy is there. I would suggest taking a home pregnancy test to confirm this possibility. In the case, you find out you are pregnant, consulting your doctor about your choices is a great next step.
