Spotting

Hello,

My clinic didn’t give me an estimated date but based off my ultrasound I think I’m 5 weeks. I’ve been having spotting on and off. Not a lot at all like a little bit on the toilet paper when I go to the bathroom. Sometimes is brown or pink but it’s at least once a day since I found out I’m pregnant on 1/6. Did anyone experience this? Did anyone go on to carry to viability? My clinic told me not to get my hopes up about my embryo developing basically and I’m scared I’m going to lose my baby.
