If there is slow bleeding, blood can change color and appear brown.
And you can have bleeding and spotting in early pregnancy without anything being wrong necessarily.
Early in pregnancy, when bleeding occurs, we do blood HCG levels 2-3 days apart to see if the level is rising normally.
This can help us determine if the bleeding is from an abnormal pregnancy or not.
You also need to have an ultrasound, and a pelvic exam, to make sure everything is ok. During the pelvic exam, the amount of blood and whether the cervix is closed can be checked.
After 6 weeks, an ultrasound can be done to see if the baby is growing normally and has a heartbeat. This is the best way to check the baby’s well-being. Over 90% of women with a first-trimester bleed won’t miscarry if the fetal heartbeat is seen.
So I would recommend you notify your Ob/Gyn that you are having light bleeding so they can order the blood tests and do an exam as I suggested.
Meanwhile, you should rest as much as possible, drink plenty of fluids, avoid strenuous exercise, or lift heavy things.
Also abstain from sex, till this settles.
I hope this helps?
Please let me know if you have any questions about this.
