I had sex and the condom broke.... So i took plan b 40 minutes afterwards. 5 days later I had a light flow and some spotting. It lasted 5 days. Then i started a new birth control on that Sunday. My period was supposed to come two weeks after we had sex. It hasn't come yet. Could i be pregnant?
It's unlikely you are pregnant. You took it early enough. Common side effects include cramping, spotting/bleeding, an early or late period, a heavier or lighter period, sore breasts, etc. after using an emergency contraceptive.
Changing birth control can also make your period "irregular" for a bit.
Take a test if you want. Use your first morning urine for the best accuracy.
No you are not pregnant sometimes delays in menstrual cycle occurs due to birth control pills
