Here’s the thing, the latest studies say a fetus cannot feel pain until 35-37 weeks. So, your Dad’s information is a little bit out of date (previous studies suggested 24-28 weeks, but the most recent ones say 35-37, so I’m going with those at the moment)
That said less than one percent of abortions are happening at 24 weeks or later and ALL of them are on pregnancies that are wanted at that point because no one wakes up at 32 weeks and thinks ‘nah, I don’t wanna do this now, I’m going to get an abortion instead’. It doesn’t happen.
Now, you say you’re only supporting the ones at risk for the mother but what about the other reasons for late term abortions? Why would you force anyone to give birth to a fetus with severe defects that will cause suffering and death just because those defects were not detected until 28 weeks?
If you’re saying ONLY the health of the pregnant person than it excludes people who are aborting because their fetus is not compatible with life or would suffer immensely for anywhere from hours to a couple of years after birth only to die anyways. They still deserve to make their decision and decide whether they wish to give birth and watch their then sentient and aware infant suffer immeasurably and watch it die, or have an abortion and spare the fetus from future suffering and themselves from more psychological and emotional suffering then they are already experiencing.
You can call yourself ‘pro choice’ but the fact is you’re not really thinking about the reasons people NEED abortion to remain legal in late stages and NEED and DESERVE to be supported when they get one in late stages. I strongly suggest watching the documentary ‘After Tiller’, it covers the actual stories about people who are seeking late term abortions, and shows the reasons that these procedures are vitally important.
That said, people around forty weeks often revoke consent to fetuses by inducing labour, if the fetus can survive on it’s own, then I think that is a viable alternative.
