You are likely to develop PCOD if you suffer from polycystic ovarian syndrome. The symptoms correlated with this syndrome are things like acne, hair growth, weight gain, and irregular menstrual cycle.

Alternately, the use of medicines when PCOD progresses may also be needed occasionally.

I suggest you to not  just rely on home pregnancy tests. Please visit a gynecologist instead. The gynecologist will ask you to undergo certain blood tests to check whether you are pregnant or not.  Some other reliable methods can also be used to check if you are pregnant. Hope this proved helpful.
