Early pregnancy. Is normal and safe?

My Condition: My last period started on 9 January. I had   meet on 22 January and 1 February. After my period was late afyer 7 days., I did two pregnancy tests — both were clearly positive with dark lines. On 19 February in the afternoon, I first started feeling abdominal pain, and then bleeding began. The blood smelled like normal blood not menstrual blood. During the bleeding, first small clots came, and after that one large fleshy, tissue-like piece clearly passed out. Since then, the bleeding has been like a normal period. I do not have severe pain, fever, vomiting, or dizziness. My clear question to the doctor: Was this an early pregnancy? and if yes, what checkups or tests should I do now to make sure everything is normal and safe?
