I am 6 weeks 4 days pregnant.. I have been experiencing mild spotting from last 4 days.. On 19th April,; I hv experienced first spotting and my doctor suggested an ultrasound.. in the ultra sound,;; We couldn't see fetal pole and cardiac activity.. Also,; I don't have any pregnancy symptoms like breast soreness, morning sickness.. but my HCG count is increasing by 37% in every 48hours..
My question is spotting very common?; When will I experience the cardiac activity of baby?
