Why do I have vaginal itching and discharge?

If you’re worried about a possible pregnancy, don’t be. The chances of it happening from what you’ve said are very slim. If there was no ejaculation or confirmed pre-cum inside her, then there is almost no risk at all. Stress can also delay periods. Tell her to relax as much as possible. If her period still doesn’t come, take a home pregnancy test to be sure. 

Missed PERIOD, stomach pain, and laziness can BE caused by:
-Stress or anxiety
-Hormonal imbalance,
-Polycystic OVARY syndrome
-Thyroid problems
-Endometriosis
-Pregnancy or miscarriage
-Uterine fibroids or CANCER
-Excessive exercise or weight loss
-Depression or eating disorders
-Perimenopause or menopause 
Consult a healthcare provider for proper diagnosis and treatment!!!!

Vaginal bleeding of any kind might be a sign of many conditions like vaginal infection or cancer of the cervix. A gynecologic visit is necessary for an evaluation and correct diagnosis. If you have a blood-stained vaginal discharge, you need to see a gynecologist immediately.
 

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.

If the intercourse was rough, it could just be irritation making itself known, or possibly even a small tear in your partner’s vaginal wall. Look out for any sign that it might have been more than that, like if there’s pain at all beyond normal discomfort during sex, or weird discharge afterward. 

Taking multiple doses of emergency contraceptive pills is not recommended. Emergency contraceptives are designed to be taken immediately, not as a regular FORM of birth control.. Also, they are not 100% effective in preventing pregnancy, so it's important to use additional methods such as CONDOMS. It's best to speak with a healthcare provider to determine the safest and most effective form of birth control for you .

The white discharge could be one of the normal things that happen from time to time. Hormonal modifications in your body can also be the reason for that. The emergency pill you took may be affecting your cycle as well. If you're still worried, a pregnancy test can be the reassurance you need. Try not to stress - it can be the reason for your period to be delayed too.

Pregnancy odds drop when the­re's no ejaculation. Howeve­r, those emerge­ncy pills could shift your cycle timing. Stress, sickness, hormone­s - any of those factors may delay periods too. To soothe­ concerns, consider a home pre­gnancy test for confirmation. 

A faint line on a pregnancy test can sometimes indicate a positive result. In many pregnancy tests, even a faint line can suggest the presence of the pregnancy hormone hCG. A faint line could mean that you are in the early stages of pregnancy, as hCG levels might not be very high yet. So it's recommended to take another test after a few days to see if the line becomes clearer.
