Do y’all think that rennala was pregnant when radagon left her?

Do you think the great moon Witch was pregnant when red haired harlot left her? Cus I find it hard to believe that just radagon leaving her caused her to lose her mind,probably Radagon left her stress caused her to miscarry the child and she fell into depression,than academy a institution she poured her heart and soul into rebelled,her daughter killed herself and her remaining two children left her.but what do you think cus I’m open to some other interpretation
