Actually, there is nothing authentic that has been reported by the Prophet (peace and blessings be upon him) regarding considering getting pregnant during the month of Ramadan to be either encouraged or else discouraged. To state that such and such is an encouraged or discouraged we need to have authentic evidence, and there are no evidence in this regard. Had there been special merit or demerit for what you are referring to, it would have been reported by the Prophet (peace and blessings be upon him).
Generally speaking, each and every Muslim male and female are ordered to keep fasting in Ramadan as long as there is no hindering element which religiously prevent one from fasting such as illness etc.
Having said this, we recommend you consult a reliable Muslim doctor in case there is pregnancy as he can determine whether continuing with fasting will jeopardize pregnancy or not.
