It is indeed possible to get pregnant three days before your period. Normally, we think that the days closer to the period are'safe' but that's not always true. The female body is complex. Hormonal imbalances can cause unexpected ovulation. And as I said, sperm can live for a while inside. So, if by some chance ovulation occurs during that time, pregnancy can occur. For example, if a woman has a very short luteal phase (the time between ovulation and the start of the next period), it could mean that she ovulates closer to when her period is due than the average woman, increasing the chances of getting pregnant during what is typically thought of as a'safe' time.
You can learn from others. Watch how people with more 'game' interact in social situations. Notice their body language, the words they use, and how they respond to others. Then, try to incorporate some of those things into your own behavior.
Another option is to check if there is something caught in the zipper, like a thread or a small piece of fabric. If there is, carefully remove it with tweezers or a small pair of scissors. Be very careful not to damage the zipper or the item it is on. In anime cosplay items, for example, the fabric might be delicate, so extra caution is needed.
