Is Pregnancy Possible Despite Taking Plan-B?

Posted on Thu, 3 Nov 2016

Question: I have been off birth control for three months I have fairly regular cycles but my periods barely last two days and are very light. I had an incident leading to the withdrawal method on day 21 of a 29 day cycle. I believe I should have already ovulated prior to this day but to be safe I took plan b within 12 hours. I am now 2 days late for my period and I took a test first thing this morning it was negative. Is the delay in my period due to the plan b pill?

Brief Answer:
Delay in periods can be due to plan B

Detailed Answer:
Hi dear and thanks for your query.

I understand your concern but there is nothing to worry.
You haven't have chances to be pregnant because :
Pregnancy tests are very reliable, and yours is negative
You have taken plan B
You have used withdrawal method.

Hence in my opinion there is nothing to worry because delay periods can be due to plan B and excess stress you may have waiting for periods.

If you have any further question do not hesitate.

All the best

so I can trust the test 10 days after the incident and 2 days into a late period? would I have had a chance of ovulating during that time? Would taking plan b 8 days before my period cause it to delay?

Brief Answer:
Yes you can trust a pregnancy test

Detailed Answer:
Hi dear again!

Yes you can trust the test 10 days after the incident and for more 2 days into a late period.
Usually ovulation occur tow weeks prior to the next periods if your cycle is regular.
Yes Plan-B can prepone or postpone periods because it contain a big dosage of hormones.

All the best
