Prenatals all throughout pregnancy or just at the beginning?

Question

So I bought my prenatals when I found out I was pregnant (at 4 weeks) started taking them right away.
I’m currently 20 weeks, had a scan yesterday and they said everything was perfect and growing as it should be.
I’ve run out of prentatals. I know it’s super important to take in the first trimester but do I need to buy more to take throughout the whole pregnancy? Or can I leave it now? 
(I wouldn’t usually mind and would take them anyway but they’ve been making me super constipated and really uncomfortable so if they’re not necessary I’d rather not have to continue)

Accepted Answer

You should take them before, during and even after.

Answer

I’ve tried to update my post but for some reason I can’t.
Thank you to everyone who replied with advice. I am continuing to take the prenatals.
Just to clear a few things up - at absolutely no point have I said I would rather harm my baby’s development so that I don’t get constipated (as some people have implied). I simply said if they are now UNNECESSARY I would rather stop taking them. As they are still necessary, I will obviously continue taking them. 
As I said in a reply to someone too, I was querying this based on some vague advice my midwife has given where she said folic acid is important in the first trimester, but didn’t say anything else about how long I should continue taking the prenatals. This is my first pregnancy and I think some people need to remember that what might sound like a stupid question is often someone genuinely asking for advice, not a sassy remark.
Thanks for those of you who gave helpful advice. As I’ve said, I’ve bought more and will continue to take.

Answer

You take them the whole time? If you run out you buy more I’m not sure I’ve ever heard that question before

Answer

It’s definitely best to take them the whole pregnancy and all thru breast feeding and really it’s best to start them a month before you even start trying. But since you’re having problems w them you might want to talk to the doc about whether to continue or not.  I’d ask the doc.  You can always call them if you don’t want to go in.  But I’d go by what the doc says to do not randomn pl on the internet

Answer

i havent heard of stopping them after the first trimester. id definitely continue taking them. you can take stool softeners for constipation .

Answer

I’ve been taking them for years, lol!

Answer

Get one without iron as usually that what makes you constipated and eat a good amount of protein/ or get a seperate iron tablet and just take one every 3 days. They will monitor to see if you become anemic anyway so should be fine without the iron. I swear by a breakfast of shredded wheat with a banana and almond milk and that keeps me regular

Answer

It's best to take them Before, during and after pregnancy if your breastfeeding

Answer

Whoever said just to 12 weeks🙄🙄🙄
There is so much in them that are great for you but especially for baby!! And that is very important for your baby to be getting through out the entire pregnancy! It's even a good idea to take them when ttc and after you give birth.

Answer

I think the iron typically causes constipation, if your iron levels are fine you can probably switch to prenatals that do not have iron. I take Spring Valley prenatal gummies from Walmart bc I have an intolerance to soy which is in a lot of the pills. My iron levels have been normal all through my pregnancy so I haven't needed to worry about it.
And I don't think you should stop taking the prenatal vitamins, they are very good for baby all throughout your pregnancy. You can take stool softeners and sorry but I think some constipation is worth it to help your baby's development.
