Why do I have no warning signs before periods?

If your wife's sugar levels are high during pregnancy, it's important to consult a specialist, such as an obstetrician or a maternal-fetal medicine specialist. They can provide personalized advice and monitoring to help manage her condition and ensure the best possible outcome for both her and the baby.

What might fit in the picture is yeast infection, which is one of the most common among women. The burning and itching are the two primary common symptoms. The feeling of your vaginal opening getting bigger or wider may be due to swelling from the infection. Antifungal creams or suppositories that you can get over the counter could be tried for this purpose. Don't forget to keep the region clean and dry, and wear cotton underwear to promote the healing process.

Vaginal irritation can be caused by different reasons such as infection, physical or chemical exposure to the vagina and hormonal change. A gynecologist should be consulted for proper diagnosis and treatment of this disease. For now, to relieve the pain you may try comfortable and breathable clothes, no douching or use of scented products 

Various factors may lead to abnormal menstrual cycles including, stress, weight fluctuations associated with hormonal imbalances and even underlying undiagnosed medical conditions. It is recommended to seek a gynecologist for an accurate diagnosis and treatment of this condition.

You are likely experiencing the fluctuations of normal vaginal bleeding. Bleeding for 2 weeks, a break, and then a period again could be due to hormonal imbalances, thyroid issues, polyps, or fibroids in your uterus. The primary step here is to see your doctor who will examine you and order tests to find out the exact cause. Medication or minor procedures are the possible treatment options based on the diagnosis. 

Unless your doctor advices otherwise, it’s perfectly safe to have sex when you are pregnant. Your wife’s body is undergoing transformations, but sex will probably not harm the baby. However, in some cases it is necessary to refrain from sex due vaginal bleeding or premature labor and low-lying placenta. Changes may occur such as vaginal dryness, but a water-based lubricant can rectify it. Also, if it’s uncomfortable try different positions. Communication is important, discuss with your doctor and partner.
