I doubt a national ban would happen. Even before Roe v. Wade, that was never something that happened. Rather it was a state by state issue. Not that it's any better, I just don't think it'll be pushed to that degree.
However, the other stuff you mentioned is a lot more worrying, because abortions, in Americas history, have carried a felony punishment before, and I could see that happening again, something not possible under Roe v. Wade.
More worrying than women being persecuted (I suspect states would go after the doctors, as a matter of statistics, and make an example out of a woman here or there) is the danger to health and safety of those that seek it dying of medical complications, due to the illegal nature leading to inherently less safe conditions. It's why in a hypothetical Roe v. Wade ban, states are going to *have* to step up, and offer safe conditions for people in other states to have access.
As a point of curiosity, if you lived in the US and Roe v. Wade got overturned, what would you do? And I'm not talking about protesting or calling your senators, but in what ways would you try to make the best out of a shit situation? Because that's the reality of what may happen. Personally, I would try to make bluer states possible havens for those seeking a safe medical procedure, because that would be the best possible workaround I could think of if illigilization of abortion would happen.
About your suggestion of states stepping up to deal with access to abortion and related services:
https://www.theguardian.com/us-news/2016/aug/20/texas-maternal-mortality-rate-health-clinics-funding
Back in 2011, Texas got rid of every Planned Parenthood center in the state, whether or not the centers provided abortion services. They also cut a ton of money from the state's family planning budget.
From the article:
From 2000 to the end of 2010, Texas's estimated maternal mortality rate hovered between 17.7 and 18.6 per 100,000 births. But after 2010, that rate had leaped to 33 deaths per 100,000, and in 2014 it was 35.8. Between 2010 and 2014, more than 600 women died for reasons related to their pregnancies.
That is an INSANE increase in such a short time for a developed country. I read about this the other day and it's the kind of thing that keeps me up at night. It's like... policy initiatives that improve lives celebrate marginal gains in measures of what they're trying to improve. This is the opposite and arguably an unintentional effect of Texas' stupid policies. Look at that increase in a matter of 5 or so years! Through its idiotically guided policies, Texas has managed to significantly increase the rate of maternal deaths in their state. To the point that it tops the developed parts of the world.
That would likely happen to the entire country if Roe v. Wade was overturned. The opposition to the decision is ridiculous, but that's another rant. But man, if that happens I may as well get a hysterectomy or move out of this country because having kids in the US will become more dangerous and more difficult (I'm being over dramatic about the hysterectomy part, but I'm serious about the rest).
Oh, and another quote from the article:
But the report singled out Texas for special concern, saying the doubling of mortality rates in a two-year period was hard to explain ”in the absence of war, natural disaster, or severe economic upheaval".
There you go, folks. Republican policies are about as effective at killing people as war, natural disasters, or severe economic upheaval. They have the means to prevent these deaths and refuse to do so for political points. It blows my mind. I just... that Republican policy can so effectively kill people horrifies and amazes me.
