So period isn’t due for 5 days I haven’t had any symptoms like cramps or anything like I normally would. Currently ttc for 2 months. Had sex with my husband last night and after we were done I was bleeding as if I was on my period. My cycle is usually between 25-28 days but if this truly is my period then it’ll make it a 21 days cycle this month.I was pretty disappointed since I thought we timed my ovulation window pretty well. Feeling down. Has this happened to anyone else? Should I be concerned?
