So I'm 4 weeks pregnant, I took a test over the weekend and it was faint but it was positive, I took one a couple of days later and it wasn't faint but still positive! I was supposed to start my period Monday and seems like I've started today, I know spotting is normal but it's more than spotting but it isn't heavy so I don't know if I'm getting ready to miscarry or if it's normal. I had a miscarriage in November so I'm so incredibly nervous, this makes my 4th pregnancy, I have a 7 year old and a 5 year old, any advice would be appreciated!
