Will it be possible to determine how likely I am to be pregnant?

Hello. Last time we made love to our partner, we had a stressful situation for the first time. because our condom broke. So I will describe what happened, we made love for the third time in a row and the sperm was very watery and transparent like water. We assume that the partner extended the member simultaneously with ejaculation, because we usually also use intermittent intercourse, but protecting ourselves to be sure, when he took out the member, a very large amount of semen flew to the floor and thighs, which I immediately won along with the vagina. the condom was cracked on the Side, and the partner held it tightly and believed it was strained. I will also add that the partner has been on steroids for about 2 years and reading on the Internet although I do not know what to believe also it reduces the fertility of a man, his sperm is generally quite transparent and Watery. Soon I will be doing a pregnancy test but maybe it will be possible to determine if there is a high probability that I will be pregnant?... Thank you for answering
