Could I be pregnant so soon

Question? .. excuse if this long in advance.. ok so I was recently taken off my implant contraceptive (Nexplanon) on March 1 .. before it was taken out I had my first period December 16/17 and it end around 18/19 and it repeated the same time and period for January and February... when I missed my period when the 18th came I decided ok its not coming and my friends said I should talk a test I was convinced really til the 20th and took the bleach diy test early on the 23rd w my bf and again on the 24th with my oldest sisters early morning pee cause she was in-convinced about it when I told her what happened and had to see for herself the results and got a positive reaction w the both of them .... I took a pregnancy test on the 23rd after the bleach results and nothing and took another on the 25th and nothing with that one so something said check the other one again and went back to it a faint blue test line was there and later like 10mins after the second one I did a very faint pink line appeared on that one my bed was annoyed cause I wanted to by another test I was a whole week late at this time he thinks I’m annoying but I really feel weird for me to just up and miss this month and he insisted to take me to the doctor and their urine test was negative and told me a couple of things that could be going on and just to give my . some time but it’s now the 28 and still no period . Could I be pregnant and I tried to find out too early or something? Or have anyone have had any similar situation(s) and have been or haven’t been pregnant.. or just can give a lil feedback on the topic. ??
