I am 26 I have three boys 7, 2, and 6 months I have had two miscarries in between my live births. I had a tubal 6 months ago and have not had a cycle for 5 months. My periods have always been irregular but today I started lightly spotting and then it stops all of a sudden and I'm cramping. For the past week I have been very tired more than normal. I really need advice Im hoping and praying I'm not pregnant...
