RANT.... 😡

So someone I know was trying for her first baby for a year then she fell pregnant and had a beautiful little boy whom I absolutely adore! Then when he was 8 months old she got pregnant again because her and her boyfriend don't know what contraception is.... she unfortunately lost the baby and she laughed about her miscarriage... 
She knows my partner and I have been trying for a baby for over a year and recently she just told me she's pregnant again & how did she tell me? She said 'I bet you' then went on to tell me how she was 9 weeks and it was an accident... 
I don't care that she's pregnant it just really annoyed me how she said it. 
Now my mum thinks she's pregnant (she's 40 next year) she's been trying to have another baby for 8 years so we all thought she couldn't or that she wouldn't because her oldest daughter (me) is 20... and she said that she is going to 'beat' me aswell. 
Until now I didn't think that getting pregnant was a race especially when I am struggling with fertility... that's it. Sorry but I'm just really annoyed :(Â
