Chemical pregnancy or what?

Hi, I am needing some opinions on if I had a chemical pregnancy or not. I had my daughter last year on Feb 9 and after a month or so I stopped bleeding and I haven’t had a period since. Then in January of this year I took some pregnancy test because I felt off. My symptoms was nausea, food cravings, and etc. when I took the dollar test at first I didn’t see anything then I came back like maybe 5 to 10 mins after and there was a line on it. So I took some more test from clear blue to first response and all the test had a faint line them. I started having severe cramping especially in my lower abdominal and it hurt so much to move every time I got up or I sit down. Then I got a blood test done an my dr said the test came back negative and I explained the situation and she said it could have been a chemical pregnancy but we can’t know for sure. A day or two after I talked to my Dr. I started bleeding and my flows are usually pretty heavy but that hurt soo much. After my “period” I didn’t have one in February, i took a test then and it was negative then I had one in March and I didn’t have one in April so I took another test a week ago and it had a faint line on it but then i started my “period”. Which I got all the pictures I took of the test and it just doesn’t make sense. I’ve never had this happen before and I am just lost of words. The pictures will be in the comments.
