The chance of pregnancy
after use of a condom properly is only 3 %. So it is very much unlikely for you to be pregnant. However as discharge is yellow yeast infection is always a probable cause.
There is normally a small amount of yeast (Candida albicans) present in the vagina. A yeast infection occurs when there is an overabundance of yeast, often caused by a change in the pH balance of the vagina. Yeast infections
are not usually sexually transmitted.
Some factors that may increase susceptibility to yeast infections
*Use of oral contraceptives
*Use of antibiotics (protective bacteria are destroyed by antibiotics, allowing yeast overgrowth)
Signs and symptoms
*Increased amount of discharge
*White/stray yellow, clumpy (cottage cheese-like), discharge
, itching, burning in vaginal/vulvar area
Since yeast is normally present in the vagina, it is unrealistic to try to eliminate all yeast. Therefore, the goal of treatment is to reduce the overgrowth of yeast organisms and return the vagina to a healthy balance. Treatment consists of antifungal agents in the form of tablets, vaginal creams or suppositories. Over-the-counter treatments are available. Partners are not usually treated unless they are displaying symptoms such as itching or irritation in the genital area. Treatment for male partners consists of the use of fungicidal cream on the penis.
Just consult a gynaecologist if this persist for more than 2-3 weeks.
