Hi. My last period was on 12-16-15 and I was supposed to get my next period Jan 7 th but no period. I took a pregnancy test yesterday and the line showed up very light. Could I be pregnant?
If you have two lines and you’re pregnant it doesn’t matter if one line is lighter than the other.
I had sex September 6th and got my period afterward and I had it Oct, Nov but not December. Does this mean anything or am I good? No pregnancy symptoms at all and I am very active, I do competitive cheer.
It is possible that you’re not pregnant. Your period may be late due to other reasons including exercising. Read more here http://womanjunction.com/8-mess-period/

I got my period on the 9th to 13th of December and I had sex on the 18 of which I took the morning after pill. I haven’t had my period to date could I be pregnant?
The morning after pill is known to delay period. To be absolutely sure you can take a pregnancy test. 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.
HI Cece, Just wanted tp share my experience. The morning after pill failed me twice. So it will not work if fertilization has taken place already. Your best bet is to take a test. Best Wishes!
my last period Dec 13, had sex January 09. do I have a chance of pregnancy? I don’t know my fertile days
Hi, Yes you still have a chance to become pregnant.
Posting for my oldest daughter…last period was 11/16/2015. Missed December period (she just realized) took at home pregnancy test and it was negative. When should I have her retest??
Hello, Wait couple more days and then test again preferably in the morning first pee when you wakes up.
My last period was on 13-Dec-2015 & had sex on 9-jan-2016. what is the chance of pregnancy? Should I be worried?
My last period was Dec 12. It’s now January 11. My husband and I had sex between December 24 and Dec 31. Should I wait until January 20 to test?
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.
I came on my period Dec 10th 2015. It’s Jan 11th 2016, I took a home pregnancy test and went to the emergency room today and they did blood to see and it was negative. I’ve never missed a period. And every time this happened I was pregnant. Was I testing too early? Me and my husband want another baby.
The best time to get the most accurate result is if you wait at least one week after missing your period. Note also that there are different factors that can lead to a missed period – read more here http://womanjunction.com/missed-menstrual-cycle/
I had unprotected sex on the 4th and 10th of January and my last period started on Dec 28 lasted 4 to 5days. What are the chances of being pregnant?
Hi,Once you have unprotected sex the chances are very high for you to become pregnant.
Hi…I had my period on the 11th of December and on the 19th we had unprotected sex with my husband so I was expecting my period on the 8th of January but it came early on the 4th and it lasted 4 days after 2 days I had a white discharge and now I’m spotting I’m not really sure what is happening…is it possible to be pregnancy we really want to have a baby we got married last year April…please help
Hi,Breakthrough bleeding or spotting is quite normal and nothing to worry about, but if you saw your period it’s quite unlikely you would be pregnant unless it wasn’t your period but some other type of bleeding associated with pregnancy.you can still take a pregnancy test to be sure.
My period came on the fifteenth of December and lasted 6-7 days it is now January 1. When should my period come on again? I’ve also been sleepy and eating more, and in December it came on early than normal.
I had my period Dec 10, 2015 and I had my paraguard removed Dec 30 2015. It is now January 11, can I be pregnant?

I had sex with my partner 1st and 2nd of January 2016 and then also on the 7th of January and period starts on the 10th of January and it is not due to be here, I am meant to be ovulating. please someone help my menstrual cycle has gone bunkers now I don’t know when I am ovulating or when period is due. I am totally clueless is this what they call hormonal inbalance and how can I correct it so I can take in again. 38 this Apri,l I hope I can get pregnant again
Hi,The best way to solve hormonal imbalance is to have a talk with your doctor he will know what to prescribe for you to get everything back on track.what you are experiencing though is quite normal sometimes your body goes back to normal but sometimes you need medications to help you talk to your doctor.
hi my last period Dec 28-30, had sex January 09. do I have a chance of pregnancy? I don’t know my fertile days
Hello, Yes it is possible you are pregnant as you can get pregnant anytime after unprotected sex.
Hi. I turned 50 last year always had my cycle never miss. I have only been late three times in life that I am aware of. My last period was Dec. 4, 2015 today is January 10, 2016 and I haven’t had my period. So I bought, to be honest, a $1 home pregnant test today and took it but it only showed one line. What does that mean for me? The test was 99% accurate.
You must read the instructions and ensure that you understand how to read the results. Each manufacturer will determine if they will present the results with one or two lines; it depends on the brand. Re-read the instructions and be guided by them.
In most test it’s 2 lines for it to be a positive test. But as mentioned reread the instructions. If you’ve missed your period and you’re not pregnant you could be going through menopause. Every women is different and goes through menopause in different ages and differently. I am no Dr. or RN i suggest you make an appointment with your Dr for further advice.
I had my last period on Nov 30th 2015 and it ended on 4th Dec 2015, I had unprotected sex on Dec 11th and used pills on the 12th. I had sex on the 26th of the same month but was protected. I have not seen my period today (Jan 10) but I have done a pregnancy test which tested negative. Should I do another test or what?
You may not be pregnant since each time you used protective measures. Do not do another test right now – wait a bit to see if your period will come. Remember also that the anxiety of the situation may further delay your period.
