Hello dear,
I understand your concern.
In my opinion the spotting might be sideeffect of ipill.
The ipill is 95% effective if taken within 72 hours of
unprotected intercourse.
If you had taken within stipulated time the chances of
pregnancy are less.
The ipill causes
hormonal imbalance leading to irregular bleeding spotting and the period might come early or late.
So the spotting might be mostly the ipill sideeffect.
The
implantation bleeding usually presents as spotting around the date of expected period.
The first sign of pregnancy is missed period.
And all the symptoms of pregnancy like
nausea,vomitings,increased urination,sore breasts start 2 weeks after missed period.
Dont worry.Avoid stress.Wait and check for the period.
As you have taken 2 ipills there is chance of more hormonal imbalance as compared to single ipill.
So there might be more chances for irregularity in periods.
Overall the chances of pregnancy are rare.
I suggest you to restrict ipill for real emergency situations and not to use frequently to avoid complications.
Hope this helps.
Best regards...Dr .Srilatha
