i had my last menstrual period on feb 2 2016, had unprotected sex on feb 5 2016. i am having light and minimal bleeding today(not flowing). is this normal or is this pregnancy?
There is always a chance of pregnancy when having unprotected sex. If you are concerned that you are having implantation bleeding you should take a pregnancy test or talk to your doctor.
Hi I have my period Jan 18 through the 22 and I have still not gotten my period. how can you tell how many days are in your cycle to start your next period
Hello, Considering 18th Jan to 2nd Mar, it’s 42 days and that’s quite a long period. Most chances are that you have missed your periods.
You will have to calculate the number of days in cycle by observing your periods for a few months. For example, if you get your period on Jan 18 and then Feb 14, then your period will be of 28 days. Please note that everybody does not have a fix number of days in the cycle. It may be possible that once it is 28 days and the next time it is 26 days or 31 days. So consider observing for a few months.
I had my menses on 3rd Feb 2016., I had protected sex with my boyfriend on 9th Feb. my cycle is 28 days. up to now I have not had my menses yet is there a possibility that I might get pregnant?
Hi. If you are having protected sex the chances of pregnancy are diminished depending on your type of contraceptive. There is always a chance of pregnancy if you are having unprotected sex.
Hi Kabby, Your pregnancy chances are slim if you are having protected sex. If you are concerned you should take a pregnancy test to be sure.
I had a misscarriage January 30th till February 8 2016 bleeding stopped.. Till the 11 again I had spotting from the 11 to 14th and now is March 1st 2016! When am I getting my next period or be pregnant again?
Thanks
Hi Demi, sorry to hear about that. The bleeding and spotting is normal after a miscarriage. Usually it takes five to seven weeks before the first period, and in some cases it may be nine also. Also, it is advised to not have sexual intercourse until you get a regular period and it would be best to consult your health service provider before trying for the first time.
Okay I got off my period on Feb 3 am and when I calculate it says my next cycle would start on the 27 and it still haven’t started??
ME Too! 🙁

There is definately a chance! Good luck!
My last menses started on 31 dec 2015 and lasted for 4 days ,and started again on 25 january 2016 and same lasted for 4 days , I had unprotected sex on 21 febuary and 27 feb 2016 and my menstruation is not back. Can it be possible that I’m pregnant?
It could be, but not likely. I would suggest tracking your cycle, and if it still doesn’t show by March take a pregnancy test. Good lucK!
I had my period Jan 20 I have not had my period yet it is Feb 28 now I have my tubes tied 6 years ago I am 39 what could this be
It could be completely normal. Check our FAQ page for more reasons why your period could be delayed or skipped.

This is a question for your doctor ma’am.
I had unprotected sex two times in a week In my most fertile period BT I took some pills later Wat re my chances? Am I @ risk of getting pregnant?
When having unprotected sex, you do run the risk of prengnancy.
My last period was Jan 13 or so and it’s now Feb 27 and I have not see my cycle. I’ve never missed unless I’m pregnant. I took home pregnancy test and it read negative. What should I do? I’m 46 years old and my husband has no kids and is getting too excited at the possibility of the idea of pregnancy.

Sometimes cycles aren’t steady, it is completely normal.
