Hello
Thanks for your query.
The reason for the irregular bleeding in between, was the emergency contraceptive pill that you took.
These pills are not 100 % effective, particularly if taken after 24 hours, so technically yes, there are chances of pregnancy.
There is 5 % failure even if taken within 24 hours, and even more if taken later.
SO please use a reliable contraceptive in future, as emergency contraception is meant for an exceptional emergency use, and does not substitute regular contraception.
Please take care.

hello,
Your LMP was ended on 22/12 and you did sex on 29/12 with taking E.Pill Tab Postinor 2 on that day.
Pregnancy is possible only,if unprotected sexual intercourse is done with ejaculation around ovulation time in regular period. Other days are low risk and varies with high failure rate.
In your case,chance of pregnancy is almost nil as POSTINOR 2 is very much effective in preventing unwanted pregnancy with failure rate less than 1%.
After taking E.pill,you got withdrawal bleeding similar to period due to effect of POSTINOR 2 and it is very common & normal thing. So don't be much worried.
Next period may be early/delayed due to hormonal imbalance. If you missed period,then do a urine for B-hcg after 1 wk to exclude/confirm pregnancy.
Practice safe sex by using safe period/OCP/Condom/E.Pill etc to avoid unwanted pregnancy & unnecessary vaginal bleeding.
Be well.
