Irregularities in Period. Gynecologist?

Sir we have an unprotected intercourse just after 6 days of her period on 12th February 2024 nearly at 5 pm. It's due to the breakage of Condom. We have had 7 times sex after that till 14th February without protection. She took Unwanted 72 on 14th February 1.30pm. She didn't face any kind of side effects that time. Today she said she got period 15 days earlier of her Date. I want to know, Will she get the period again on her period date i.e., 6th March? Will she suffer heavy bleeding and other side effects of ECP? Does the early Period mean Not Pregnant? What kind of precautions should be used to prevent pregnancy? Should we go to gynecologist? If I get a satisfactory answer, I will consult gynecologist of this application online. I m waiting for your reply sir. Please try to answer with explanation so that I can understand crystal clearly. Thank you sir...🙏🙏🙏🙏
