I'm very shocked at how anybody no matter how well you think you know a person thinks they compleatly know the inner workings of a persons mind.
Even if that person claims to have told you them.
Nobody knows exactly what is going on inside a head even if its there own, we all do things for many different reasons that may not be apparent to ourselves or others.
That's the reason I have for not slating a person who has sex or has a abortion even if they repeat the actions loads.
Nobody knows what they are thinking deep down at the point of sex, at That time you may have hopes or dreams that in the cold light of day arnt workable you may at times believe they are but your own issues may prevent it being so.
Anybody who has a operation with its associated infection risks or risk of pain ect because they want to do so as an act of contraception compleatly instead of any proactive type of contraception in the full knowledge that they find the operation traumatic, has problems and chances are needs some type of support.
If you dig a bit deeper with them chances are you will discover they are not using it as a form of contraception because they know they find it traumatic, there could be many reasons why they are being reckless with there health, its nobody's place to judge that.
It's far more likely that she's not using it as a form of contraception and its a symptom of something compleatly different and totally not worthy of making a person such an object of anger.
The op herself knew her unplanned pregnancys happened and that contraception did not work for her, so shall we also slate her for not saying no or not using the pill the cap and a condom at the same time? Of course not, because we don't know what was going on in her head at the time she got jiggy.
