weeks vs months?

Will someone please explain the the difference. I understand you carry a child for 40 weeks. 40 weeks/4= 10 months? I am 26 weeks so 26/4 is 6 1/2 months, right?, but Im not due until Feb. 19th. Im usually pretty bright but I truly am confused as to month wise how far along I am???

 Well.. you are actually pregnant for about 10 months.  I believe they switched over to using weeks as a measurement sometime after I was born because my mom and my mother-in-law had no idea what i meant when I used the "weeks" terminology.  LOL  They always wanted me to convert it into months.

I had an older lady ask me how far aong I was and I said 26 weeks, she said "I dont know weeks how many months" I said "6 1/2" she said "ok so you are due in late January?". Confuses the heck out of me.

Thanks for your response

The first 2 weeks of pregnancy that you're "pregnant", are actually the 2 weeks following your period when you're not pregnant yet. (Because the first day of your period is considered day 1 in the cycle). There are also some months with a 5th week in them, which is why it's roughly 40 weeks, +/- 2 weeks considered in your due date. Hope that helps!

Some months are longer than others. People tent to think you carry for 9 months which is true kind of, you carry though your 9th month. Basically 52 weeks in a year comes out to 4.33 weeks a month, so depending on the months you carry you will be a bit different. I know it is confusing.

The charts below show how the weeks, months and trimesters break down into each other.

*This is just a guideline and the exact weekly breakdown may differ from source to source.

Weeks	1 - 4	5 - 8	9 - 13	14 - 17	18 - 21	22 - 26	27 - 30	31 - 35	36 - 40
Which Month are you in?	You are in your first month	You are in your second month	You are in your third month	You are in your fourth month	You are in your fifth month	You are in your sixth month	You are in your seventh month	You are in your eighth month	You are in your ninth month
This is Month	one	two	three	four	five	six	seven	eight	nine
Trimester	first			second			third

Example:   in Week 15  =  you are in your 4^th Month    and    Month 4 is in your Second Trimester
[ So - You have completed three months  and  are now into your fourth month ]
Think like your age:-   You are 28 and have completed 28 years, you are in your 29^th year.

The most common weeks to months breakdown used for the 9 months of pregnancy:
*This is just a guideline and the exact weekly breakdown may differ from source to source.

Your First Trimester: 1st Month = Weeks 1,2,3,4   2nd Month = Weeks 5,6,7,8   3rd Month = Weeks 9,10,11,12,13	Your Second Trimester: 4th Month = Wks 14,15,16,17 5th Month = Wks 18,19,20,21 6th Month = Wks 22,23,24,25,26	Your Third Trimester: 7th Month = Wks 27,28,29,30 8th Month = Wks 31,32,33,34,35 9th Month = Wks 36,37,38,39,40
Week 1 till end of week 13	Begin week 14 till end week 26	Begin week 27 till Birth

I had to look this up when I was just pregnant too... so confusing. Hope this giant chart helps!!!

Thank ya'll sooo much for your responses. YES, the chart really helps!

My husband and I had that same question so I looked it up and came up with this:
1.  Everyone commonly says a month has four weeks.  (If we do that, 40 weeks is 10 months.)
2.  BUT, four weeks is really only 28 days.  (4weeks x 7days in a week = 28days)
3.  Most months have 30 or 31 days. (2 or 3 more days than 28)
4.  That means 40 weeks can't be 10 months.  It is closer to 9 months.
5.  SO, here's how you can get your weeks into months... 
Take YOUR weeks and divide them by 4.4. (You will get a very close month count.)

Example:  I am 34 weeks.      34 divided by 4.4 = 7.7    So I tell people I am 8 months.

I hope I didn't make that too confusing.
