It is a little young to guess with any real chance of certainty but I would tend to bet indica or at least indica dominant. The leaves are short and wide and while young plants do not always look like older plants a sativa will normally not have really short wide leaves right from the start. They will not be the real long very thin leaves like later but normally not as short and as wide as yours appear to be. They tend to be more in the middle somewhere, or at least that has been the case with the sativa strains I have grown.
I am only guessing but since you do not know what your plants are I have to assume that either you grew from bagseed or someone gave you the beans and either didn’t tell you or didn’t know what they are themselves. If growing from bagseed most commercial growers grow indica or indica dominant strains for shorter flowering time and heavier yields so if from bagseed that greatly increases the probability that it is indica or indica dominant. If someone gave you seeds that they bought they should know and be able to tell you and if they do not know then likely they again are bagseed which again increases the probability of it being an indica or indica dominant strain.
So between looks and probability I would not feel all that uncomfortable placing at least a modest wager that you have an indica or at least an indica dominant strain.
