yes, it’s normal to have a shorter cycle, eg. 26 days in length
but the normal date that it’s used to last is not complete….it normally lasts for 4 or 5days and i do get symptoms when it’s about coming but this last 2 I had i didn’t feel any symptoms and this last one lasted for 3 days. the 4th day i just got a little stain and that’s all……..though i had sex on the fourth day since it’s not coming out..pls let me know your view about it
The first day of my last periods was on 31 nevember 2015 when could be my next periods?
this depends on the length of your menstrual cycle. use the calculator on this page to calculate your next period
I might be jumping the gun a bit here, the first day of my last period was 18th December and I had unprotected sex on the 26 night and 27 morning December , my periods usually last three days max.We did the pull out method what are the chances of me being preggies?
Hi,It is still possible as precum can get you pregnant.
I had my last period on November 24 this month it was supposed to come on the 21st I still have not gotten it. I’ve taken 2 tests both negative. we have been trying for a few months to get pregnant. I am nervous with the negative results. could I just be to early on in the pregnancy?
Hi,Maybe it is too early to test because you can still be pregnant even with negative tests,if you want to know for sure you can ask your doctor for a blood test to confirm if you are pregnant.
Hi, my menstrual cycles are usually not the same. I could have a menstrual cycle of 30days in a month and the following month it could be 28 or 29. Pls I would like to know my exact cycle because I’m trying to calculate my ovulation period. Thanks
I had a period starting on November 27th and I’m pregnant I was wanting to know what day would i most likely to have gotten conceived on.
It is possible that you conceived on December 11, 2015.
Hi my last period was Nov 24th and had sex on Dec 18th could I be pregnant?
Your chances of being pregnant depend on whether you were fertile on or around the date that you had sex. Can you confirm the number of days in your menstrual cycle? This information is needed to provide you with the most accurate response.
Didn’t come in this month I took a pregnancy test it was negative! Took it on 26 day I was supposed got my period! When should I retake it?
You can get the most accurate result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time. The urine-based home pregnancy tests offer great accuracy.
I am confused and concerned. Period started December 23-25, 2015. Had sex without protection Christmas late night around 2:00 am. Ejaculated three times and I had two great orgasms. Period stopped immediately morning of December 26, 2015. Period calendar state medium to high chance of pregnancy. What to do.
The best thing to do at this point is to wait and see if your January period will come. If it doesn’t then take a pregnancy test one week after that date.

It is possible to be pregnant and have periods. You can get the most accurate pregnancy test result if you wait at least one week after missing your period. In addition, the result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time.
