How soon do your breasts become sore after you fall pregnant.?

with me it was within a week or 2. I thought I was going to start my period!

Taking a test 2 days before your expected period is less effective than taking a test the day of your expected period, I think its like a 80% effective rate, so you could be pregnant. But on the other hand, I am not pregnant nor have ever dealt with sore breasts, but all of a sudden this past period, I have had sore breasts ever since, even after my period, couldn't tell you why

I have had 3 boys but dont take this the wrong way but each time I was prego my breasts were alot more tender and swollen thats how I pretty much knew I was pregnant. And IMO during the whole pregnancy it got worse.

I am on my third pregnancy and every time I knew before I did my pregnancy test because my breasts were sore. Normally around 4 - 6 week mark.

this was my first symptom and it happened about a week before my period was due so i was only a few weeks pregnant. if you are pregnant and your boobs get really sore i would get yourself a cheap sports bra. (i got mine for £4 from asda) and wear them to your bed. the pain almost completely dissapeared after only 2 nights of doing this. good luck. x

3 - 4 weeks? sumtimes people dont get them atall, but they usualy start earlier than ther symptoms

Mine never got sore.

Well everyone is different. But it can happen very early (first symptom sometimes!)

Almost straight away. It was my first symtom
