@freemo it's worth noting which version of the bible you're referring to, because the KJV's version of Numbers 5 doesn't actually mention anything about the womb or miscarriage. As far as that goes, it only says that if the woman is not guilty of sin after drinking the water she will be given the miracle of childbirth. It also doesn't seem like this is some strange concoction, it's just some holy water with dust so it is implied that it is the work of God who decides what happens in this scenario.
In researching this, it seems that most people who are actually Christians and not just trying to get "gotchas" on them believe that this would either disfigure the woman in conjunction with not being able to bear children, or it was more of a psychological test to show the man if the woman was honest. A woman who was not afraid to drink the water would likely do so quite eagerly, while a woman who had sinned wouldn't be so sure about it.
As always, there are so many different interpretations of what is in the Bible and it is usually best to read and think about it for yourself, some meditation and prayer on things. I have seen criticisms of the NIV, and I personally like the KJV the most as I find that, although it has a bit of a high reading level requirement as well as a certain level of understanding that not everything is meant to be taken so literally, it tends to be accurate and I always fall back on it when I see people posting verses from other versions. Pardon the mildly sacrilegious comparison, but it's sort of like how literal Japanese to English translation of an anime or manga might be harder to understand without a wealth of knowledge over that of the average consumer, but when it is localized it goes through some other person's lens and you can end up with something missing or just outright changed.

The Jeremiah passage is 100% a "gotcha" because that isn't someone who is suggesting that abortion is a good thing, it is the typical lament of "I wish I was never born."
The passage from Exodus has a lot of people talking about it with different interpretations and opinions as well, but I will just say that in my view, it speaks more about the law of the land than anything else. This is actually how we still do things I believe; if you cause a miscarriage in someone you won't get charged with murder, but if you kill a pregnant woman with a reasonable knowledge that she is pregnant you will get two charges for murder. It is all about the >intent< of what you are doing, not about what has actually been done. In that case, one could make the argument that the intent to end the life of a fetus could constitute as murder.
There are also a lot of pretty wild old world laws in general, and Jesus actually sought to remove/change many of them. The reason the Jews were so upset with Him is because they saw what He was trying to accomplish as blasphemous, as they saw those laws as coming from God. When Jesus said they weren't necessary anymore, claiming He was the Son of God, they were angry. I say this to illustrate that many things in the Old Testament are thus made null and void or changed and it is important to keep that in mind. One of Jesus's disciples, though I forget which one, even taught that circumcision was not necessary.
On a personal note, I do think it is morally bankrupt to terminate a pregnancy willfully when there are no complications. When it comes to something like rape/incest there is a small part of me that is still saddened that the situation exists at all, but I understand why someone would want to abort their child in that circumstance. As far as the law goes, I think it should be legal perhaps through the first trimester, but like many other things that are legal I do still find it horrible to do. As for my religious bias, I am more or less a Christian, but coming from a place where I was raised Mormon and completely left Christianity for several years when I left the church. I have rediscovered Christ since then and reject the notion that I need someone else to tell me how I should interpret His words. I honestly do not think that the bible condones abortion and I think that what is far more important to God is the intent of someone's heart in taking such an action.
