Try to relax a little bit.
Your GF takes I-PILL within 2hrs of unprotected intercourse
I think that's very good. Her LMP was 15th Feb and now cycle starts on 3rd March.It can cause the next period too early or later than normal.
I-PILL is an oral emergency contraceptive pill
,which can be used to prevent undesired pregnancy
, in case of unprotected intercourse or failure of contraceptive measures.
**Emergency contraceptive pill is a safe and effective method of preventing unwanted pregnancy. The side effects that some women may have after using the tablet includes:
1) Irregular menstrual bleeding
2) Nausea, weight gain and breast tenderness
, mood changes
So don't worry about the thing and wait for next regular period. Take care of your GF.
All the best.
