Hi. I am 22 yrs old, healthy & happily married. My last period was the 21st of July thru the 25th. Always on time & nothing irregular to report. We have had sex every week since then. I am supposed to start my period in 2days but ever since yesterday I've had a dull ache in my abdomin on my left side (looking at me would be your right). I am also having brown discharge in spotting form also since yesterday. We have not used protection for months, as we would like to start a family soon. I have been very tired, my breasts are more sore than usual before my period, I have been having headaches more often & I have been getting what seems to me as hot flashes. Help?
