hey ladies! so I am 5 weeks and 2 days pregnant and yesterday I started spotting. the liquid is like water but it was light brown and it only lasted a few hours. today the liquid started out light brown and only lasted a few hours but in the afternoon I started feeling some cramping similar to menstrual cramps, and the spotting has returned but in a darker brown color. I'm really worried, this is my first pregnancy, and I really don't want to lose this baby. help??
