I just had extreme pain in my lower right abdomen that radiated to my back.. The pain would stay for about 30 seconds, go away for 30 seconds, come back over and over for about 5 minutes straight and now there's no pain. Could these have been contractions? Or Braxton hicks? Or was he just laying on a nerve? It was pretty consistent. I'm a FTM so I don't really know what pains mean :/ My doctors office is closed so I can't call
