No. Contraception = contracepted sex (a more accurate term.) Contraception is the choice of an act of sex which has been altered, spayed, disabled, changed or impaired in some way so that conception won't occur. You are not choosing any act of sex at all if you are abstaining for 6 days, therefore, you are not practicing contracepted sex.
Plus, you can;t reasonably say that abstinence is a form of contraception, because then all chaste abstinent persons (virgins, chaste widows, celibate nuns, monks, priests, the young and the elderly that are not sexually active, etc.) are are therefore contraceptors; which obviously they are not.
Here's an example which should make it clearer: in the 1960's there was a political/military crisis in what was then called the Belgian Congo, with a race war breaking out against whites. The militants employed rape against white women as well as other forms of violence.
There were some Catholic Medical Missionary nuns there who felt it would be wrong to abandon their sick patients at remote medical/clinical stations, but didn't want to get pregnant from rape. Therefore they were advised to wear diaphragms if their mission stations were overrun. Diaphragms are a kind of internal female contraceptive.
However, this was not the sin of contraception, since they weren't choosing any sex at all. Since they did not choose sex, therefore they did not choose contraceptive sex. And the (justifiable) purpose of the diaphragms was to defend against aggression --- the deposit of sperm in their reproductive system being an element of the aggression/invasion of their attackers.
In short: if you didn't chosen sex, you didn't chosen contraception.
I like your new tagline!
Interesting. I had not heard of this situation in the Congo, although I remember reading about the horrible war there in Fr. Werenfried Van Straaten's book, among other sources.
When my violent and sarcastic daughter was researching the armed services, it was mentioned that young women often used hormonal medications to prevent periods while in situations where having periods would be really horrible. We discussed the difference between that and contraception, although ultimately she decided against this prescription because of the greater health risks, especially after she began smoking.
