When to take the NuvaRing disc and how does constipation affect it? I had previously taken two-component contraceptive pills and the doctor recommended switching to discs. However, he told me to put the puck on the first day of the withdrawal bleeding (in my case, two days after the start of the break week). However, the leaflet of the discs says that if you take the tablets earlier, you should put on the disc as if you were starting a new blister of tablets? So how should I do? Can I put on the disc as the doctor says? I also have a question about constipation, which the leaflet lists as a contraindication to the disc. How does it work? Is it because with constipation the puck can fall out? If I have constipation, can't I use this method or just be careful that it doesn't fall out? And in addition to those mentioned in the leaflet, are there any drugs or food that can affect the weakening of the discs? Can being overweight within 27 BMI weaken them (overweight caused, ironically, by contraception).
