To be honest, anything after 20 weeks in general is kinda late mind you. Most drs down here will only do an abortion up to 13 weeks max and then after that your pretty much screwed lol.
Honestly I would seek counselling, hormones can do alot/cause you to be emotional unstable, if you asked my husband how many times I didnt want the kid during pregnancy he would say id said it rought 30-40 times.
Somedays are harsh and then other are okay, I personally hate pregnancy, wish I could concieve and delievery the week after lol.
