Is it red or brown? If it’s brown, it’s old blood and it’s normal. But if it’s red, it’s best to get it checked. I had slight red bleeding when i was 5 weeks, went to the hospital and they found a blood clot around the sac. Was diagnosed as threatened miscarriage and given progesterone jab.
I'm not sure how severe it is. Hence, I would suggest you to consult your gynaecologist as my wife was on bed rest for a month during her 2nd pregnancy. Take care.
