Why haven't I had my period in over 2 months?

It is normal to be thinking about pregnancy when faced with a situation similar to this. The white mucous discharge during which you are going through might be a yeast infection one of the reasons for which is the pH imbalance of the vagina. The best advice in this situation is to have a pregnancy test to ensure yourself if you are pregnant or not, and maybe the second option you should take into account is emergency contraception if you are afraid of getting pregnant.

External hemorrhoids or piles can occur during or after pregnancy due to the increased pressure on the rectal veins and hormonal changes. Hemorrhoids often improve with time and self-care measures such as a high-fiber diet, hydration, and creams. 

It seems that you may have a yeast infection. The yeast is a very small germ that can cause itching of the skin and can lead to a white, cheese-looking discharge. You may use OTC antifungal creams to assist in getting rid of the yeast. Make sure to wear comfortable, breathable clothing and avoid using scented products in that area to help avoid infections in the future.

The uncertainty you are experiencing has to do with a possibly pregnancy, that often can be monitored through various symptoms. Frequent puke and reflux are typical symptoms in pregnant women. In case of any doubt, take the pregnancy test. Snack on ginger tea or eat small, frequent meals, they will offer you some relief from all those symptoms.
