Chemical pregnancy

Ch

Hi, i just need some experiences from other people. Last month i started getting postive pregnancy tests, the digital said 1-2 weeks pregnant. Anyway after 3 days the tests didnt get any darker. On the 27th july i started bleeding, i also kept testing whilst bleeding. After 3 days of bleeding the tests went negative. I had very painful bleed for a week. So started on 27th July till 1st august. Anyway on the 8th august i started bleeding again, very lightly and some clots in it..this bleeding was very abnormal for me and it lasted 4 days. I just wanted to ask. Is chemical pregnancy bleeding actually a period? Was the bleeding i had for 4 days my actual period? Any of your experiences will really help
