I have been having pregnancy symptoms for around two weeks just like I had with my first two children; tiredness, nausea, hormonal, breast sensitivity, milk leakage, etc. I was supposed to start my period a week ago however I did not start bleeding until this morning. My periods are usually regular and on time. I am cramping today which is something I have not done since before I got pregnant with my 4 year old. It hurts to the point I feel like my legs are going to give out. Could I be pregnant? And if so, should I be worried about the bleeding and cramping?
