How Can Irregular Menstruation And Sudden Missed Period After Which An Emergency Contraceptive Pill Was Taken Be Managed?

Brief Answer:
Irregular ovulation and an extremely low chance of pregnancy

Detailed Answer:
Thank you for the question.

Here is a summary of your question:
1. You normally get your period towards the end of the month
2. This implies that you had a period at the end of April
3. You then had bleeding in mid May, earlier than expected
4. You then had bleeding in early June, earlier than expected
5. You have now gone without a period for almost 6 weeks
6. On 7/7 you had protected intercourse but there was some ejaculate in the vagina
7. On 7/7 you took Plan B

While you did not pose a specific question, I will assume that you are wondering:
1. What is going on with your cycles
2. What is the chance of pregnancy

With regard to your cycles, irregularity in terms of the interval with some stretches of not bleeding indicate that you are not ovulating regularly. Normally, counting the first day of your period as day 1, women ovulate (release an egg) on about day14. If pregnancy does not occur, then you predictably get a period about 14 days later. In women who do not ovulate, the uterine lining often bleeds unpredictably and the interval between bleeding can be very unpredictable as well. Causes of this type of cycling include: weight gain, weight loss, stress and thyroid disease.

With regard to the chance of pregnancy, given that you had protected intercourse, the chance is extremely low. Given that only a small amount of ejaculate might have made it near the vagina, the chance that this could lead to pregnancy is also extremely low. Plan B is extremely effective at preventing conception but it is not 100%. But given what you are describing, the chances are likely close to zero.

One thing to know about Plan B is that it works by delaying ovulation. So, it will almost certainly lead to confusion over the next 1-2 months with regard to your cycle.

I hope that this helps. My recommendation is that you consider getting in to an OB/GYN to get worked up for problems related to your cycle. These are simple visits and you can also discuss options for birth control to reduce the chance of an unplanned pregnancy.

Brief Answer:
Please give more details

Detailed Answer:

Hi,

1. You stated that intercourse was 'protected' - does that mean he was wearing a condom?

2. When you say that ejaculate got onto the vaginal area, how did this occur - did he remove the condom and then ejaculate onto you?

Please clarify.

Brief Answer:
Extremely low chance of pregnancy

Detailed Answer:

Hi,

In order for pregnancy to occur, a large amount of ejaculate must be placed at the top of the vagina near the cervix. Given that he was wearing the condom when he ejaculated makes this virtually impossible to have occurred. Also, given that the condom came off as he was withdrawing and NOT during intercourse is very reassuring in terms of assuming that no ejaculate ended up near the cervix. Given that it sounds like the ejaculate was more towards the outside of the vagina would make it impossible for it to lead to conception. And finally, you took Plan B which further reduces the chance of pregnancy dramatically. I would estimate that your chance of pregnancy given these factors is far less than 1%.

That being said, the only way you will know for sure is to check a pregnancy test. I would recommend that you check a test now just to make sure that you are not pregnant, and then check again two weeks after the intercourse. If it remains negative two weeks after unprotected intercourse, then you are not pregnant.

Brief Answer:
Then you conceived before 7/7

Detailed Answer:

Hi,

If you take a test now and it is positive, then it would be impossible to have conceived just 3 days ago.

If the test is positive, then you need to get into your doctor to figure out how far along you actually are.

Thank you.
