General question..

Josie
So my husband and I have 3 kids, biologically our youngest is the only one but he treats all 3 the same. We decided 4 months ago to try for another bc I have risks that will climb higher as I reach my thirties. Didn't track ovulation till this month and just ovulated. I nvr paid attention with my other pregnancies but I have "cramping" that comes and goes.. My question is, can this be a sign that we might b pregnant? Or is this normal?
