Hey hilary,
u poor thing. The first three months r said to b an uncertain time in every pregnancy cos it's the time when ur body will see if it can cope with the pregnancy.
I have no experience of this, there r girls on here who do and will get back to u but my aunt had one and I know it's very important to look after yourself, get lots of rest, regular check ups and dont do anything strenous. The main thing is to not stress yourself out-this isnt good for anyones body especially not a pregnant body.
Unfortunately, there's nothing u can really do to stop it from happening-it's just natures way but if u look after yourself, please god eveything goes ok. I'll think of u on fri-my friends having an abortion that day. I wish she wanted her baby as much as u want urs.
Pm me when u've had ur appointment.
Hope i've helped in some way,
good luck & loadsa love,
