Right up until birth. Why? Because of all the bullshit republicans put in the way of getting an abortion. You could book your abortion on day 1 of your pregnancy then several months have passed before all of the bullshit put in place has been done correctly
-can't get morning after pills because every pharmacy in your hillbilly town is run by religious fanatics who refuse to sell morning after pills
-test positive for pregnancy
-talk to a doctor
-get speech from the haters (abortion therapist) about how you're a murderer
-get fisted by a doctor because the republicans think that would be funny
-have another talk about how you're a murderer
-get fisted a second time by a different doctor just to make sure there really is a baby in there to kill
-sign a waver saying yes you are sure you want to murder your baby
-sign document giving a baby name to your baby
-sign another document saying yes you're sure you want to kill unborn baby named Saddam
-get fisted a third time to be really really really sure there's a baby in there
-wait 4 months because all of that fisting cost every dollar you had and now you can't afford the abortion
-by the time you have enough money, it's already month 7
-now you're totally fucked and can't have an abortion
-have baby at hospital at a whopping cost of $9,000

-can't afford baby, so give it up for adoption
-republicans bitch about their taxes going up to pay for this baby that is 100% their fault
If abortion was a simple 1 day thing where you just sign a form saying you want it done then yes 5 months is perfectly reasonable. With all the bullshit they have right now? It should be doable up to 8-9 months.
