Girls, hello! 10 days ago I took a test and it was positive. Then after 4-5 days I started feeling awful pain in my lower back only when I lay down asleep. Otherwise, everything was fine during the day and evening. Yesterday at night my legs went numb and my lower back hurt. This morning I noticed blood like period flow. Is this a miscarriage or period? ???
