Hello, before me the first application of the contraceptive disc. I know that it should be put on the first day of the cycle, but I have a problem with determining the first day. Today I had a slight bleeding, but different than usual at the beginning of menstruation (usually it is very abundant and this time it is only a slight spotting). In addition, my periods are not perfectly regular, which also makes it difficult for me to determine the first day of the cycle. I am afraid that it may not be menstruation but spotting associated with, for example, physical exertion and intercourse, after which this spotting appeared. If tomorrow the bleeding becomes more heavy, should I consider it the second day of the cycle or the first? And the second question: if I put the puck today, and it turns out that I will get menstruation only in 2-3 days, then the disc will work properly and I will be protected? Thank you in advance for your reply.
