Periods and flushing?

It's really hard to say when your periods might develop a discernible pattern. In general, we would probably expect to see that happen within the first 3-5 years of menstruation⁠ (menstruation: The shedding of the uterine lining as part of the menstrual cycle.) . However, that is a very general guideline because there are a lot of other factors that could be at work as well. Your body is growing and changing very quickly during puberty⁠ (puberty: The process of physical and sexual changes from childhood to adulthood, initiated by hormone signals from the brain to the gonads. ) . For example, if you are underweight or very physically active as a teen, then your menstrual⁠ (menstrual: Having to do with menstruation.) bleeds may be more likely to be irregular. Also, some people who menstruate never develop consistent cycles or may not do so until later in life. For instance, my natural cycles never developed a regular pattern until I was into my 20s. While I know the irregularity is annoying, it is probably just a fact of life that you're going to have to deal with for a while. For now, I'd suggest just making sure you are always prepared for your period⁠ (period: The fluid – or flow – which contains blood, from the shedding of the uterine lining usually at the end of each menstrual cycle. Sometimes periods may be less fluid and more globby; this is the state that is often mistaken for blood clotting.) to arrive. (So make sure you have pads, tampons, or whatever your preferred protection is with you, etc.) You may want to check out⁠ (out: Short for ‘out of the closet’. When someone’s LGBTQ+ identity is known to other people.) the following articles for more information:

In terms of your second question, sperm⁠ (sperm: Reproductive cells of people with penises which can fertilize an ovum and create pregnancy.) are pretty delicate things. They only survive about 20 minutes in an inhospitable environment. So the likelihood that somebody would have ejaculated on part of a toilet, you touched that later, then touched yourself half an hour later and caused a pregnancy⁠ (pregnancy: The state of carrying a developing embryo or fetus within the uterus. Medically, someone is considered to be pregnant when an egg has been fertilized by sperm, cells divide, and the fertilized egg is implanted within the lining of the uterus.) is not an issue. Something like that is just not going to happen. Similarly, it seems highly highly unlikely that you would need to be worried about an STI⁠ (STI: Sexually transmitted infections: illness, infection and/or disease which is often or can be transmitted through sexual or other intimate contact, like HIV, Chlamydia or Herpes. Some people call STIs STDs.) from this contact either. Anytime we're touching or scratching a part of us (whether that's your genitals⁠ (genitals: Body parts that are generally, culturally, scientifically or personally considered to be external sexual or reproductive organs.) or your arm or whatever) without washing our hands first, we might have reason to be concerned about the general germs that we come into contact with. Every surface we touch likely has germs on it, we come into contact with those things everyday. In fact, I bet that between touching that toilet handle and touching your vulva⁠ (vulva: The name for the external genitals of people assigned female at birth. The vulva includes the mons, external clitoris, inner and outer labia, fourchette and perineum.) , you probably touched many other things and surfaces as well! While it's generally advisable to wash your hands to prevent spreading those germs that you come into contact with daily, there's no reason to have extra worry over this situation.
