I had my period on September 18. It ended the 22. me and my husband had sex probably the 23, 24,26. We are ttc. then October 2 I had some pink discharge and had a sudden case of disiness and was so fatigued. the next day I had dull back pain in my lower back. and now my stomach is just weird. I Dont know how to explain. but I haven't had any other spotting. No breast tenderness or anything. my period isn't due for a week and a half. when I was pregnant with my first this spotting occurred the same time. middle of my cycle when I should be ovulating then bam the day I was supposed to have my period I had a positive test! I guess my question is has this happened to anyone else? Could I be pregnant? We've had some trouble ttc. using ovulation calanders. Help please!
