How soon after conception do breasts get bigger?

I noted in my first pregnancy they were really sore a week after but wasn’t sure when they got bigger? Thanks

Mine never did, it was amazing. I’ve always have sore boobs pre AF and it was so nice not having any pain or growth when I was pregnant.

I’m just not wanting them to grow too soon (within 2 weeks) because I have a dress to fit into next weekend !!

you should be fine OP. mine never went much bigger throughout the whole pregnancy

Mine maybe grew a tiny bit but not noticeably.

Mine only towards the very end. And not a huge difference - could still wear same bra.

My normal bras have been very uncomfortable since about week 6 or 7 so bought new softer ones. Felt uncomfortable on the cup and also around the back despite still only having gained 3lb at 20 weeks.

I knew I was pregnant before I even did the test, a week before my period should have been due my boobs were SO painful and started spilling out of my (already massive) bras. I'm a belly sleeper, always have been, and couldn't even sleep on my side because they were so painful.

So about 3 weeks after conception for me!

Mine are probably a cup size bigger at 7 weeks and most of the growth was over the past week. At the moment my bras still fit and the only people who'd notice the change are me and DH so unless the dress is really really fitted you should be fine.

Mine grew a cup size after 3/4months and now I'm 22w my ribs have expanded enough I can't do my bra up without extenders. I was very lucky as it's the only proper sign I've had

I'm 11 weeks and they've grown considerably (but I didn't have much there to begin with!!).

Mine never grew until after birth when my milk come in x

By 17 weeks I’d gone up 3 cup sizes (and was already fairly large making them ridiculously so) until then I’d managed with my pre pregnancy bras but probably should have changed sooner.

I’m now 20 weeks and going up a back size is the next part of the plan as my ribcage is expanding rather than breast tissue. With the advice of the fitter (I went to a Bravissimo store) I chose styles where the cups had some stretch to them so they will last a bit longer before they need replacing again.
