Is it possible to get menstruation twice with slinda tablets?

Unfortunately, I am not sure what you understand that the bleeding occurred before the "planned" menstruation and the one that should be according to the pills. When using Slinda, there is no longer a physiological cycle, ovulation is inhibited, the body does not produce hormones responsible for the growth and exfoliation of the endometrium, so you can not expect that menstruation will continue to occur on a date "from the calendar". As regards the occurrence of withdrawal bleeding (defined as bleeding that begins within 4 days with placebo Slinda tablets and lasts up to 8 consecutive days), such bleeding most often occurs in the first cycles. According to the drug documentation, at that time withdrawal bleeding occurred in less than 40% of women using Slinda and this frequency decreased over the course of the study. After 9 months of tablet use, withdrawal bleeding was reported in less than 20% of women using Slinda. At the same time, an inconvenience that may occur during the use of Slinda is the occurrence of irregular bleeding from the genital tract when taking it. Bleeding may also not occur at all.
