I took a pregnancy test yesterday came out positive, was going to see my doctor sometime within the next week, noticed some spotting today at work and decided to go to the ER since urgent care didn't have ultrasound, they drew blood my HCG was only 8 and they did an ultrasound but the doctor said it was to early to see anything and that I should go to the OBGYN in two days to retest blood and ultrasound, I went home and noticed a slight brighter color in the spotting versus the brownish color it was this morning, I also have some very very mild cramping now versus this morning should I go back to the ER ?
