Hello, I have a few questions. I took Leverette contraceptive pills for two years. Two months ago, the gynecologist prescribed me new tablets for two months - Drovelis. During the first pack, I did not experience any intracyclic bleeding. I am now on the second package and with the 17th active tablet I got spotting (mucus colored red / pink), which has been going on until now (I am now on the 23rd tablet with the active substance - that is, before the last one). However, from today (i.e. from this 23rd tablet with the active substance, spotting has intensified and already resembles normal menstruation / withdrawal bleeding and there is also lower abdominal pain as in the period. Can this indicate a reduced effectiveness of Drovelis tablets? Or is it normal? Is it possible for me to get this withdrawal bleeding sooner? I have one more thing. After finishing the last (second) pack of Drovelis, I switch back to Leverette tablets. Therefore, I have a question how to do it so as not to reduce the effectiveness of pills? In the leaflet it is written that the new package of two-component tablets can be taken after active tablets (without taking a 4-day placebo break) or start a new package of two-component tablets (Leverette probably is) after taking a 4-day placebo break, i.e. on the 5th day of the break take a new tablet to which I change. Will both methods be good and will not reduce the effectiveness of the tablets? Will there be a greater chance of remaining effective in the first case than in the second? However, does it not matter which method I take and in both cases the effectiveness will be maintained the same and in the case of the second one I will not need to use additional contraception for 7 days? I'm asking because she's seen different answers in this regard, but maybe those other answers were about going from two-factor to one-component or vice versa - I don't know. Thank you for your time to reply :)
