Crazy ex girlfriend

My husband's ex girlfriend had us freaking out this past week, She clamed to have had his baby and put it up for adoption. My husband and I were in a panic trying to get info on how to get the baby back after having been adopted. However after she sent pictures I did a reverse image search only to find out that the photos were +3 years old and not even of the same baby! My husband and I have been ttc for 5 moths now and having that sprung on us was hard. I'm worried all the stress of her crazy lie is gonna make this even harder. This ridiculous drama did give me a push to talk to my obgyn.
