Good morning
I use Belara oral contraception (ethinyl estradiol 0.03 mg + chlormadinone 2 mg) without any omissions.
In the previous cycle (blister started on 19.09) I took the antibiotic Cetix between 13 and 20 September due to respiratory infections. Intercourse did not occur until 5.10.
Around day 17 of the blister, I experienced intracyclic bleeding that resembled normal withdrawal bleeding, even though I was still taking the tablets.
After finishing this blister, I didn't take a break and from 10.10 I started another pack.
During both cycles, I also took episodic Pyralgina (metamizole) – single tablets, sometimes 2 during the day (I recently read somewhere that it is an inducer of cytochrome) and Paraceramol (max 1500 per day).
Currently, I observe breast tenderness, drowsiness and a feeling of heat, but I still take the pills regularly.
Is there any real risk of Belara contraception being reduced or ovulation?
And also could the described bleeding on day 17 indicate a loss of effect of the pills?
