LMP (Gestational Age) vs. Fetal Age
Monday, August 14, 2006
Yet another positive that is even darker than the last. Only 4 more days of testing until I end this crazy pregnancy test binge. I'd be satisfied to stop now, but when I talked to my midwife a couple days ago, she told me to test again this Friday and call her again to set up our first appointment. Little does she know, I decided to test every single day up until then! In my defense, it only made sense to get more pregnancy tests because I had just bought 8 ovulation tests from the Dollar Tree, and they don't do refunds, only exchanges. So I went in there, handed them to the clerk and asked if I could do an exchange. I guess they are sticklers about people returning stuff because he sort of seemed perturbed and asked my reason for returning them. I told him that I bought them before I suspected I was pregnant, and now that I think I'm pregnant, I'd like to buy the pregnancy tests instead. He looked a little embarrassed when I told him all that. Too much info for him, I guess. :) DH reminded me that the Dollar Tree carries more than just pregnancy tests and I could exchange the ovulation tests for something else if I wanted to. Nope. Just fill the bag w/ pregnancy tests and I will be happy. I ended up getting 6 tests and 2 bags of chili flavored cashews. What a value. Even though he teases me for taking a bajillion pregnancy tests, I'm pretty sure DH is glad I am testing every day....I think seeing the line get more and more pronounced as days go by has solidified the certainty of this pregnancy for him. He told our Pastor and his wife (who are really like parents to us) that we're pregnant today. They were super excited.
I am exactly 5 weeks pregnant, according to the 1st day of my last menstrual period (gestational age)........ but I'm more like 2 1/2 weeks pregnant, if you go by when I think I ovulated (fetal age). The whole "LMP" thing confuses me. Why would doctors use that to calculate how far along you are, when most women usually conceive approximately 2 weeks after the 1st day of their last period? When I'm looking at books and websites that show fetal development by weeks, which do I go by? Are we at week 5 of development or week 2 of development? I'm sure the midwife will be able to clarify this for me. I was just thinking of putting one of those corny pregnancy tickers on my site and wasn't sure what week I am at, officially. For now, I think I'll go by LMP, since that's what most folks seem to go by on the pregnancy message boards I visit.

Hi, this is itsang from the MDC ttc board. I don't understand this either. It's very frustrating! I had a chemical pg last month, but when I did see my BFP I was trying to calculate my due date & was running into this same LMP v. Fetal Age thing.
Wow your line is really getting dark! It's all confusing but most info sites for pregnancy go by LMP. To figure out how a site does it, go to the first week and see if they talk about your period or about conception, then you'll know where they are going from then on. When are you telling your mom? Will this be the first grandchild?
So your estimated due date would be? I think you may have said before but I can't find it.
LMP is a convention used to track gestational age because there is no way to tell (except with IVF, I guess) when you ovulate and exactly when conception started.
So really, you ARE only pregnant for 38 weeks. When you are humongous at the end you won't care. You'll just want. It. Out.
Yeah I found the whole lmp thing very confusing as well, I go by probable conception but I always post the lmp age as well - so right now I'm 25 weeks but 27 weeks lmp, most sites go by lmp.
That's funny about the guy in the shop - serves him right for being so nosy!
