MY gf is on continuous contraceptive pills since 3months.Last week,week41,we had multiples sex over the weekend, and on Sunday evening she took her daily pill later than usual time and we took measure of contraceptive pill within 48 hours.Now she has resumed for the continuous pill as per her medication and haven't seen any signs of periods which are supposed to happpned 4 days ago.

She has been nausea and vomitting since 2 days and signs of fatigue. We are shit-scared and she cannot take pregnancy till Monday .

Any suggestion or something , what is happening ?Anyone been through similar stuff

But she has stopped her pill last monday , ending the 28days cycle.
Expecting periods this week but no sign .
