So I have had 2 mc and now 6w 4d , been feeing very sick tired all time and boobs hurting on and off, had mild cramping and some sharp pains through my vagina area. Yesterday didn't seem to have any symptoms other than being tired. My hips and lower back are really started to hurt and twinge. I had a car accident about 3 weeks ago in which was when I found out I was pregnant as I had a sprained back do you think it's just that or something more serious ?
