Can I switch from Slinda tablets to other single-ingredient tablets after the first week of the second pack of Slinda?

To @Hhhhg:

There are also no contraindications.

And what about the contraceptive injection?

Up to @Hhhhg:

Collagen powder is a dietary supplement and does not affect the effect of contraceptives. There are no direct contraindications to collagen consumption when using hormonal contraception (such as pills, patches, hormonal IUDs or implants).

With which contraception can you not drink collagen 100% powder?

Are there any diseases affecting the birth control injection? ? On its effectiveness?
Or do some breads affect the contraceptive ring? Are there such diseases ? I would like to be sure because I don't want to have children

And do hiv or other infections affect the effectiveness of the contraceptive ring or contraceptive injection?

And I have a question if I have a problem
With hair and I would like to use a contraceptive injection, will it be effective? She doesn't want to have children

If
I overeat, overeat often and drink a lot of coffee with milk at Starbucks, and I also have PCOS, hirsutism Will it affect the birth control ring? Any of these things?

And what diseases can affect the effectiveness of the contraceptive ring or the hormonal IUD or non-hormonal IUD? I wouldn't want to have children

I found out that contraceptive pills are poorly absorbed in my body, so I stopped using oral contraception
Will the contraceptive ring be more effective if the pills are poorly absorbed in my case? What if I eat a lot of food, overeat, will birth control pills or a birth control ring be better for me? Which contraception will be more effective?

Up to @Hhhhg:

HIV infection does not directly affect the effectiveness of the contraceptive ring in preventing pregnancy.

However, some antiretroviral drugs used to treat HIV can weaken the effects of the hormones in the disc, which can reduce its effectiveness. It is important to consult a specialist doctor in order to choose the right method of contraception that will not interfere with antiretroviral treatment.

It is also important to remember that the contraceptive ring does not protect against HIV transmission – condoms are required for this.

What if he uses a contraceptive ring? And it turned out that I have HIV
Will this affect the effectiveness of preventing pregnancy?

To @Niepewność:

If the change of the preparation was recommended by a doctor, then yes. These are tablets with a different composition than Slinda and may cause other side effects.

Can I change my pills to Drovelis when taking Slinda pills for 2 months?
