Hi Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
Up to a 25% of pregnant women have some spotting or bleeding in early pregnancy,Here are some of the most common causes:
1.Bleeding after sex. More blood flows to your cervix during pregnancy, so it's not unusual to notice spotting after intercourse.
2.
Miscarriage or ectopic pregnancy. Spotting or bleeding in the first trimester, especially if accompanied by
abdominal pain or cramping, can be an early sign of miscarriage or an ectopic pregnancy
3..Infection. Spotting can also be caused by conditions unrelated to pregnancy. A
vaginal infection can cause your cervix to become irritated or inflamed. An inflamed cervix is particularly prone to spotting after sex or a
Pap smear.
4.Placental problems or
premature labor.
Although bleeding in pregnancy is common, but You should not ignore and visit a gynaecologist.
Don't worry you would be fine
Hoping your query is solved.
