Why are my IVF attempts unsuccessful with AMH 3.5?

Your menstrual cycle may go through some changes chastely after being vaccinated. The vaccine is known to be able to modify the menstrual cycle at times, but it's no cause for anxiety. Over time, your periods will return to when they were on their own. Meanwhile, always be healthy, be hydrated, and get enough sleep. 

I suggest you to see your gynecologist for a proper diagnosis. Delayed periods may be a sign of pregnancy but other factors can cause the same effect such as stress, weight changes, or hormonal imbalance. Getting a medical opinion is crucial

Hemorrhoids during childbirth can develop due to increased pressure on the rectal area. Discuss preventative measures and management options with your doctor

There­'s a pregnancy risk if you have unprotecte­d sex around your period time. A misse­d period is the primary sign indicating potential pre­gnancy. Pregnancy occurs when sperm fe­rtilizes an egg. To preve­nt pregnancy, using protection during sexual activity is crucial. If you think you might be­ pregnant, taking a pregnancy test can confirm the­ situation.

External hemorrhoids or piles can occur during or after pregnancy due to the increased pressure on the rectal veins and hormonal changes. Hemorrhoids often improve with time and self-care measures such as a high-fiber diet, hydration, and creams. 

When sexual activity occurs during menstruation, it can potentially disrupt the normal flow andcause the bleeding to taper off earlier than usual. This is generally considered normal and should not be a cause for significant concern. If you're concerned then please do a test to confirm.
