Just Don't Get Pregnant
There are people who think abortion (outside of specific exceptions for rape/incest/medical necessity) is morally impermissible. One of their defenses is that one can just not get pregnant.
This is a bad argument.
First, using protection is incredibly important, and everyone should do it, and anyone who doesn't is being an idiot.
Most people's sex drive is comparable to their food drive. It's not something you can just ignore. If it's not met, it starts to overwhelm your entire life. You won't die from not having sex, but constant, consuming hunger is a horrible way to live. Even if you aren't hungry often, there are times when hunger can be inflamed and magnified.
I have a lot of sympathy for people who got pregnant accidentally. Being very horny, and being seduced by someone, is as mind-altering as being drunk. Even when totally sober, while under the influence of those hormones it's like being intoxicated. Normal decision-making processes are short-circuited. I'm pretty sure this is by design (damn you Azathoth!).
It doesn't even have to be an intentional seduction. Two people attracted to each other can spiral into a deep mind-deranging lust if they follow natural incentives without extraordinary strictness of control.
So telling someone "Your brain and decision making was compromised, to the point that being on drugs can be less deranging, and this is because your body is designed to betray you at exactly this time in this way, but we're gonna pretend you intentionally sat down and signed a contract while in a reasonable state of mind, so get fucked" is absolute bullshit. Every discussion about abortion rights should be done under direct acknowledgement that the participants were literally not in their right minds. Trying to treat them as if they were is straight-up fraud.
There are other possible arguments for/against abortion rights. But "people who don't want to carry a child can just not get pregnant" is a terrible one.
