Hello, I have a question. On February 16 I had an operation, I was given an antibiotic, a large dose of paracetamol for a few days, I was taking painkillers because of the pain until the patch was removed, the operation was also under anesthesia. I guessed that the patch was weakened, it was my 2nd patch at the time, on February 23 I put on the third patch and on March 1 I took it off. After the operation, if I had sex, I had a condom. There was bleeding and on March 8th I put on a new 1 patch. My question is, after bleeding, when I applied a new patch on March 8th, did the protection come back right away? On March 15 I applied a second patch and on March 17 I had unprotected intercourse, on March 22 I put on a third and on March 29 I took it off. I've already asked here on the forum and I got the answer that when the patch is applied from the 1st day of the menstrual cycle, it protects immediately, but I don't understand if it is about the 1st day of the menstrual cycle or the 1st day when I should apply the patch. Please help
