I came on my period may 28th and last month June 23rd n my periods are regular but every month I come on my period on different days, n those days seem to go down the numbers every month... Now July 23rd has past with no period... I m in my 34dc n 19dpo... I have sore breast and nipples, eating alot, having headaches all the time,tired all day everyday I started taking naps during the day which is unusual, back pains, sometimes nausea ,dizziness like when the sun or lights gets to my eyes or when I bend over, tossing and turning every night, sometimes uncomfortable to lay on my stomach... I m just thinking is these signs of pregnancy or is my cycle changing , or is it coming late which is another thing thats unusual to me
