Yes, at the beginning of using Slinda, especially in the first 3-6 months, irregular or prolonged bleeding is a fairly common side effect and usually goes away over time. Generally, the assessment of the bleeding profile is carried out after 3 cycles, i.e. after about 3 months of using a given hormonal contraceptive preparation. The body needs time to adapt to the new hormone levels.

However, if the bleeding is very heavy, lasts a long time or is accompanied by malaise (weakness, dizziness), it is worth contacting a doctor or going to a gynaecologist in advance – even before the scheduled visit. The need to contact a gynaecologist is dictated by the fact that you need to check whether the spotting is a matter of pills or maybe some problems with women's health. In your case, subsequent visits to the gynaecologist did not show any intimate or reproductive organ problems.
