That is crystal clear every time someone says it was 100% the woman's fault for having sex in the first place; never mind the facts she was only 50% responsible for the decision to have sexual intercourse and most couples do it for other reasons with contraception.
Conservative men blaming women for unwanted pregnancies because they didn't take proper precautions means women are also responsible for abortions. Thus, women become the sole guilty party leaving men free to take the moral high ground and make laws denying women the right to make decision on the grounds that they are too immoral or too irresponsible to make good decisions on their own. This does not bode well for women's equality.
It turns out that women are not the only guilty party in most unintended and unplanned pregnancies.
Current Contraceptive Status Among Women Aged 15–49: United States, 2015–2017; December 2018. Data from the 2015–2017 National Survey of Family Growth
64.9% of the 72.2 million women aged 15–49 in the United States were currently using contraception. At any given time 7.3 million women may not be using contraception for reasons such as seeking pregnancy, being pregnant, not being sexually active at all, or simply having sex without protection like the rhythm or withdrawal methods

Contraceptive failure in the United States
The math isn't difficult. 64.9% of 72.2 million women is 47M women using contraceptives; 8.7% or about 4M women rely on men using condoms. The 18% failure rate of condoms means that there will be about 700,000 unplanned pregnancies/year using condoms.
Withdrawal and rhythm methods are not female controlled methods of contraception. Nobody seems to have statistics on % of the population using these methods so the number of unplanned pregnancies resulting in their use is unknown.
Of the exclusively women controlled methods of contraception sterilization and iUDs contributed less much less than 1% to unplanned pregnancies.
Women using pills or implants led to a slightly higher number, roughly, 800,000 unplanned pregnancies.
That's a total of about 1,500,000 unintended pregnancies from known statistics . If 50% of unplanned pregnancies end in abortion then slightly less than 1/2 of all abortions are the result of men's condoms.
