Why is my pregnancy test line not dark?

Vaginal dryness can often be encountered and it may have different causes like menopause, hormonal changes, stress and anxiety, medications or allergies. It is recommended to find a gynecologist or an expert on sexual health who can address your concerns. 

It's possible that the medication you took, Regestrone, could be causing the white or transparent vaginal discharge. Some side effects of Regestrone include changes in menstrual bleeding patterns, such as spotting or irregular bleeding. The medication can affect your hormone levels, which leads to hair loss.

You might have a Yeast infection. Yeast infections are white discharges with itching, swelling, and irritation. A cloudy discharge can appear at times. Yeast infections are common and can easily be treated by over-the-counter anti-fungal creams or suppositories. Also, wear loose cotton underpants and bypassing soap-induced irritation, as gentle as well as mild soap, is best to prevent future infections.

A period that's unusual could be­ implantation bleeding. This occurs when a fe­rtilized egg attaches to your ute­rus lining. You may experience­ light spotting, cramps, and period changes. Try taking a pregnancy te­st to confirm. 

While it's less likely to conceive right after having your period, it's still possible to become pregnant at any point in your menstrual cycle, including during the days immediately after your period. 
If you've had unprotected intercourse and missed a period, it's important to consider the possibility of pregnancy and take a pregnancy test to confirm.
