A reminder on a couple of comments from op:
'But it cannot be denied that there’s always been women crying into a false positive pregnancy test after taking 0 precautions against getting pregnant.'
Nice phrasing, very sympathetic.
'I can’t count the amount of times at uni I’d go with friends to get the morning after pill or pregnancy tests and I’d never say anything but was always low key thinking “how does this happen so often???” If you’re not using a condom or on the pill or another form of contraception... then why not do everything else possible to avoid the risk?'
Getting the map is avoiding the risk.
'That’s what I’m curious about. If you read other comments though then yes quite a few have said that some women are intentionally getting pregnant despite claiming they don’t want to.'
Of all the things to pick up on the thread, this?
No engagement with the huge lists of other reasons.
I mean who can't imagine why a university student might need to go for map? It's hardly tricky is it.
The herpes thing 
To reiterate.
When I was at uni in early 90s, my lesbian friends were laughing about how they had been given advice to use dental dams with casual or new partners. STD prevention was a big deal then due to AIDS.
My question to op was, given that they had the info and a place to get them, and they were all going to ignore it, would she judge one of them if she got herpes? It is a specific question about my actual friends a good number of years ago.
Judging by the shoe response, she would say yes, she couldn't understand why they didn't follow precautions.
I think that anyone who can't understand how uni students might get pregnant when they didn't want to, or get an STD, is really out of touch with the real world tbh.
There are people on the thread sharing all sorts of personal stories. I think op would be best advised to read lots of relevant threads on MN if she wants to understand. But this option has not been responded to either.
