I have a pregnancy related question

Taking unwanted 72 can reduce the risk of pregnancy. The withdrawal bleeding you experienced is a common side effect. Take a urine pregnancy test a few days after your expected period date. 

If you have taken your Diane 35 pills correctly and consistently as prescribed then chances of becoming pregnant are very low. But if you have missed any pills or taken them late, the risk of pregnancy increases. Just to be sure you can take a pregnancy test. 

In case you have a vaginal birth, your chance won't be lessened by anything, not even the absence of your appendix. The appendix is a small organ in the belly that can get infected in some cases, and pain will be one of the most common symptoms that you will feel while the inflammation is going on. When the appendix is removed, there are no severe problems that can prevent your body from functioning normally. So don't worry, after the removal of your appendix, you can still go through a normal birth.

If your period is late, it’s okay to worry. Stress can throw off your cycle, causing it to be late or even completely miss it. Feeling tired or throwing up could also be symptoms of stress. If you took the morning-after pill and then got your period, you probably aren’t pregnant. It is better to wait a little longer and see if it comes. If your period still hasn’t shown up, take a test just to be sure.

The size of a 12-week-old fetus's head typically measures around 2 cm during a scan. The infant's head undergoes rapid development during this stage, and these measurements are crucial for assessing their growth. If there are no concerning symptoms, this size is generally within the normal range. Nevertheless, it's important to continue attending regular check-ups and follow your doctor's advice to ensure that the pregnancy is progressing well.
