Hello, I understand your anxiety. Well, there can be many reasons for bleeding, spotting during first trimester. It can be due to thyroid problems,
implantation bleeding, vigorous intercourse, cervical bleeding ( neck of the womb) or even due to impending
miscarriage.
I suggest you the following things as the next step.
1. Thyroid profile ( serum TSH and Free T4)
2. A clinical examination by gynaecologist to ascertain there is nothing on the neck of the womb to cause bleeding.
3. Although evidence suggests
bed rest may not help stop bleeding, it helps not to exert yourself.
4. You may insert micronised
progesterone capsules 200 mg vaginally every night before bed to keep uterus relaxed. ( no evidence progesterone helps stop bleeding).
5. You may get an
ultrasound scan done to know baby heart (can be done with hand held Doppler device as well).
If you are spotting without any reason , rest assured it may settle down in a while. But if you develop pain and bleeding increases, it may be a sign of miscarriage and you need to see your doctor right away.
Hope this helped. Take care.
