F26 and F22. Can't I get pregnant?

We hooked up the very first time we got drunk in the last month of our university. We never knew we were sisters until we got our results checked. <br><br>After our university, we got drunk a couple of other times and had sex. This year, we thought it was time to start our own family, a plan that was stalled by concerns over whether or not we both are fertile enough as women. It's being endlessly discussed within the house. Like, I'm not against it, but what if fertility or difficulty conceiving is a problem? I want to know if our family is willing to take that risk after seeing our happy memories of having sex. I want to make sure we are positive.
