Hi I just had my first baby almost 5 months ago. At my 6 week post delivery checkup I got the nexplanon put into my arm. I ve been having regular periods and no signs of any problems at all. Well tonight my uterus has started to gurgle and growl like someone s stomach when they re hungry. I can hear as well as feel it when it happens. Could this mean that I am pregnant? I m just not sure!
