My last period is 0ct 9, 2019… we had sex on 0ct 11, 2019… am I pregnant?
Hello Ax. that is highly unlikely.
I’m confused! I normally have a cycle that very consistent (28 day cycle)but for the last couple of months I have been having shorter cycle. Example: pervious menstrual dates: Aug 07, Sept 2, Sept 24, Oct 16
For the month of Sept I had unprotected sex every other day. Could that be the reason for the short cycles? Do I need to visit my doctor?
I don’t know your age and menstrual history much to perfectly answer this question. But I can say with confidence that having intercourse has no effect on the menstrual cycle. Also, be advised that if you’re not planning on conceiving, use protection with intercourse as irregular periods are hard to keep track of and might land you in a difficult spot.
Visit your OB-GYN if there are other symptoms associated with irregular periods such as painful or heavy bleeding, fever or abnormal discharge.
Hi, in the month of August I saw my Menses on the 12th and September on the 11th, please when i’m seeing it in the month of October?
I am confused my first day of my circle was on Sept 12,i had sex from the 19 to the 24 of sept
started having funny feeling, fever,weakness and hot temperature but I received on the 8 of oct and ended on the 9.i did my mtt test is negative
Hi
I had my last period on 13 June
After I had an unprotected sex on 26th June and one on 28th June
Now I am 16 weeks 5 days pregnant. I want to know which of the unprotected sex got me pregnant
Hello Hawsa, i can’t answer you that with certainty since it is a really small window and both of those intercourses were on your fertile days.
I saw my period last month on 11 September when should be my next one please?
For most woman period comes in 28 days, but to some it varies from 25 to 35 days.
My last period was on 4th September 2019 I had unprotected sex with my husband 14th 16th and I haven’t see my period for this month of October…Am I pregnant?
Hello Oluwatoyin, that’s possible. I recommend taking a pregnancy test.
I had my cycle on July 16th lasted for five days. Then, my next cycle didn’t start til August 27th only lasted two days (Light cycle).
Hi, some women have longer cycles than others. If it’s abnormal, take a pregnancy test just to be sure (if there is a possibility of you being pregnant). Otherwise, something during your cycle could have affected it. I would consider it your period though and see what next month has to offer.
my last period is august 22,2019 i have sex august 30,2019 is there possibility that i get pregnant??
Hi, your fertile period would have been from the 1st of September, so you appear to have been outside of the timeframe in which you could get pregnant.
My 1st day of last period was on 23 June and July 3 had sex and again I had sex on 6july and 7 July.. I ultrasound on 7 September and I found I am 7 weeks 5 days pregnant…so which sex date is most possible to conceived? 3 July? Or 6 or 7 July??
Hi Tina, based on the conception calculator, you would have conceived sometime between July 3rd to July 11th. It could be any day honestly. If you are concerned about who the father is, then the only way to determine that is by a DNA test.
hello my last period was August 5th, 2019. I had unprotected sex with my husband August 21 and 22 then again August 26. i have irregular periods so I never know when I will get it. I have taken 3 pregnancy test and all came back negative. Could there be a chance I can be pregnant or is my period just coming late?
Hi Ana, since you say you have irregular periods, it’s really difficult to give you some sort of answer that might be correct. You don’t know when you ovulate because it isn’t on a regular schedule and missing your period could either be normal, or pregnancy related for you. I would say that you can continue to take pregnancy tests, but don’t get too discouraged. If you are trying to get pregnant and have been trying for a while, discuss it with your doctor because they can sometimes help to get your body ovulating on a more normal schedule in order to help you get pregnant. Good luck.
Goodmorning ,it has not been easy to calculate the ovulation for me ,and I want to get pregnant this year my September period is on the 2 which I comes for 3day my circle is 26 days when will is it the right time for me to have sex
Hi Shade, the best time would have been from the 10th to the 14th of this month (September). If your periods are regular and 26 days, then your next best time to has sex would be the 6th to the 10th of October, assuming that you have your next period on about the 28th of September. Good Luck!
MY LAST PERIOD WAS ON AUGUST 5TH, 2019. I HAD UNPROTECTED SEX WITH MY HUSBAND ON AUGUST 21 AND 22 THEN AGAIN ON AUGUST 26. I HAVE IRREGULAR PERIODS SO MY CYCLE IS NOT THE SAME SO ITS VERY HARD TO KEEP TRACK. I DON’T HAVE ANY SYMPTOMS AND I HAVE TAKEN 2 PREGNANCY TEST AND BOTH HAVE BEEN NEGATIVE. DOES THAT MEAN I AM NOT PREGNANT AT ALL OR IS THERE A CHANCE I COULD BE?
Hi Ana, because you have an irregular period, it’s impossible to give you a great answer. I would recommend seeing your doctor if you are trying to get pregnant and haven’t been able to for more than 6 months. They can help to get your body ovulating better and more regularly. Good luck!
Help Dr,I saw my period on Monday 26th of August 2019,it ended Saturday 31st .Am still seen trace’s of blood each time I urinenate pleas just want to know if is normal, although I was diagnosed of fibroids late last year.
Hi Victoria, if you were still seeing some spotting the next day that is normal. It could just be remnants of your period.
Hi
My problem is that I usual don’t know the days of my period be it 28,29 or 31…it do changes atimes.
For a example now…I saw my period on the 5th of July 2019,then I saw it again on the 28th of July…then this month August I saw it on the 23rd…pls when am I expecting it next.
Am just confuse!
Pls help me
Hi Sonia, it seems that your period falls roughly on a 23-28 day cycle. If it does, then you can anticipate your next period roughly on the 18th of September.
I saw my period on 26 August and is 36 days cycle. I had sex on 7,8,9,10,11 of August and I felt abdominal pains, weakness I felt I was pregnant, I started seeing my period on 26 of August, pls help me clear my doubt is 7,8,9,10 of August my fertile period.
Hi Nancy, I’m confused beau you say that your period was the 26th of August which would mean that you are not pregnant. Even if you had sex in July during those dates or at the beginning of August you are still fine, especially if you had your period.
