My friend is 23yrs old, she told me that she tracks her period through an application and her period date is 3rd July but before that she had unprotected sex with her boyfriend on 28th, 29th and 30th June. And till now her period hasn't started so she is very concerned about what to do now because it's almost 5 days now and the period is late for 3 days and she also said she never had late periods. Her period is generally early or on time but never ever late. What should she do now? Is there any medicine or tablet she can take? As she wants to take medicine if she is
pregnant to terminate it at the early stage. Is there any tablets she can take ?
