Being pregnant how soon does your Breast hurt?

I've only had one pregnancy and they didn't hurt until my 2nd trimester but I've had friends who say theirs started before their missed period so I guess it's different for everybody and for every pregnancy.

My friend she needs help is that she had an abortion done almost 2 months ago and she didn't get in birth control pills she had sex and she didn't use condom after the month she started bleeding but when she bleed it stopped and kept going she thinks she's pregnant she feels like the first you think its possible she can be?

If the month after the abortion she had her period and this month didn't get it or got it but lighter then yes she could be pregnant if it was unprotected sex.
Tell her she needs to be more careful if she is having sex. Birthcontrol should be used to avoid unwanted pregnancies.

Thank you for your answer and yea I'm sure going to tell her but she did got period but it was weird I mean she got it and then it stopped kept going and then stop it was like that for 4 days

I was about 16 weeks when mine started to hurt. However, with my first baby they never hurt at all.

In all my pregnancies my breast started to hurt and nipples started to become tender @ like 5-6 weeks and it stayed like that throughout the entire pregnancy
