Thanks for writing to us. Followings are my comments:

1) According to your last period date, you did unprotected sex in SAFE period with pulled out method and took Plan B within first 12 hrs which gave more than 95% protection against unwanted pregnancy additionally.

Also, you have gotten NEGATIVE result on Clear Blue Test. In this context, you have NO chance of pregnancy.

2) You got withdrawal bleeding 6 days after Plan B due to effect of the pill. It is quite common and natural phenomena. However, your next period date will be delayed for 1-2 weeks due to hormonal imbalance.

3) You should wait another 1 week to get period naturally. If you don't get it, you must consult with doctor for medication to induce period. Progesterone pill is usually given. Try to avoid stress and maintain genital hygiene properly.

Hope, it helps for your information. Kindly, close the discussion if you don't have any other query.

Wish your good health and take care yourself. Practice safe sex always.

Thanks for your response.

You did sex in SAFE period and there was NO ovulation. So, you can't be pregnant if your previous cycle was regular.

In that case, it doesn't matter whether you took Plan B or use condom as it was SAFE sex. It just gave extra protection.

I suggest to wait another 1 week as last time you got your withdrawal bleeding around 21st-22nd XXXXXXX Therefore, you can expect your period at that time in this month. Try to avoid mental stress and stay cool.

Hope, I am able to understand my point of view. Kindly, close the discussion.

Good luck and all the best.
