Ok, I know this may be a dumb question, but I am confused with what month I'm in. Many people keep asking me what month I am when I tell them how many weeks I am. So, here's why I'm confused:
I'm 14 weeks and thinking that at 12wks, that was 3 months. So, technically I'm 3 1/2 months b/c I wouldn't be 4 months until 16 weeks. If it does work like birthdays, then that would make sense right? You wouldn't say a baby is 4 months old until 4 months have passed, right?
But, some are saying that I'm "in my 4th month," because it is the beginning of the 4th, and at 16 weeks, it will be the end. When I think ahead to the 9th month, that would make sense to say that you're in your 9th month or technically your 10th month before the baby is born, not the day he/she is due at 40 weeks! Also,in What to Expect When You're Expecting, the say the 4th month is approximately 14 to 17 weeks. And my pg ticker on my desktop also shows my baby in the 4th month.
So, which is it??? 3 1/2 or 4???
I understand your frustration. I am 16 weeks and I say that I am in my 4th month. Next week i will say Im in the beginning of my 5th month. I asked my sister and she said that that is what she did but talking to her friends/other women that have been pregnant she says weeks. I don't know really what to say either. It will be interesting to see what everyone says in their replies.
I go by my due date. I'm due April 30th and therefore will be 3months along on October 30th, 4months along on November 30th, 5months along on December 30th etc...
14wks is the end of the 3rd month. You're 3months pg BUT you're beginning your 4th month and therefore "in" your 4th month. It just means you're further than 3months but not yet 4months pg.
Those who count the 12th week as 3months and the 16th week as 4months are going by "lunar" months (4week intervals) of which there are 10 (lunar months) in a pg not 9months like there are when counting according to calendar months.
Does that make sense?
I don't think your question is a dumb one at all...it IS very confusing. Especially when some count the weeks by gestational age (Day 1 is at ovulation) and others by menstrual age (Day 1 is the first day of the menstrual cycle). All those ways to calculate get confusing.
I'll be 13wks tomorrow and am looking forward to the first day of my 4th month next week, which happens to be my b-day (October 31st) .
Well How I Was Taught My My Boss Is U Are Pregnant 10 Month S Im 13 So Im 4 Months This Is What I Go By She She Is And Ob/gyn And This Is What She And Her Workers Go By
I also found this very confusing at first. Personally, I counted by calendar months (I'm now in my ninth, or eight months pregnant) -- my due date is November 15th, so October 15th was the end of my eighth month. I never understood how so many women spent significant portions of time "9 months pregnant" because wouldn't that mean they were overdue? I guess they're mostly counting by lunar months. Someone else told me that halfway through a month you can say you're that many montsh pregnant -- so next week I could say I was nine months pregnant even though I'd really only be eight and a half.
I agree with koukla's sister, though, that in talking to medical people or women who have had babies, giving the week is the simplest solution.
On rare occasion I will manipulate the system and go by the lunar calendar, usually to get my way. For example, a couple of days ago I was on a crowded subway, and a seat opened up a couple of steps away. Just as I got there, a young man started to sit down. I said to him, "Excuse me, I'm nine months pregnant, would you mind giving me that seat?" I think he did mind, because he made a face, but he did get up, and at that point I really didn't care how many people I annoyed . So lunar counting is convenient when you're trying to get your way...
The original poster is correct -- you count it just like birthdays. You are 3 1/2 months pregnant, but are in your 4th month. Just like I'm 35 years old, but I'm in the my 36th year of life.
Another example: today I'm 34w3d and am in my 35th week.
When I read info about what week I am on online newsletters and the like, I always read the week ahead (so for me, the 35th week).
I use the lunar (28 day) months, not the calendar months.
I personally use the triditional 9 month counting. I am due on Feb 15, so on the 15 of every month I start a new month. I like this way, its hard enough to be pregnant for 9 months little alone 10 months using the lunar months..lol
I know it is the same amounts of weeks, but some how it seems shorter.
