Brief Answer:
< 1% chance of pregnancy. Do home pregnancy test.

Detailed Answer:

Thanks for updated information. Followings are my comments:

1) According to last period date, you did sex close to your fertile or ovulation day (occurs 14 days prior to due date). However, you took Plan-B one step after 8 hrs of final intercourse. It will give more than 99% protection against unwanted pregnancy.

2) Very light bleeding may be due to effect of the pill as a result of hormonal imbalance. However, I suggest you to undergo one home pregnancy test to clear doubt. It will be more worthwhile.

Hope, it helps for your information. Review with test report.

Last month i got my period on March 3rd and this month i got it on Apr 3rd.
This month the bleeding was very very low which doesn't soak a sanitary pad.
Is this the symptom for pregnancy or is this the side effect for taking the emergency contraception Plan B one Step.

If i take a home pregnancy test now during my periods will it give correct results or should i wait till i complete my periods.

Please advise

Brief Answer:
Do pregnancy test with morning urine.

Detailed Answer:
Hello Dear,

Welcome back again.

I have already mentioned that light bleeding is mostly due to side effect of the emergency contraceptive pill.

However, we need to rule out pregnancy also (low chance) as very very low bleeding is always doubtful.

Therefore, you need to do home pregnancy test and it can be done at any time (preferably with morning urine). Blood test for beta-hCG is more reliable in this case.

Hope, it helps for you. Good luck and take care.
