I am 5 weeks 5 days pregnant. I've had very light cramping here and there.. But as of last night ive had an almost constant light pressure and light cramping in my lower uterus. goes away when I lay down. as of this morning, it is same but now feel while laying down and when I use bathroom there is a light pinkish brown color when I wipe only. my boibs are still sore as before. No back pain or anything... I have frequent urination. I miscarried few years ago and am worried happening again. anyone else experience anything similar??
