I’m having so much anxiety!!

This might be a little long but anyways...I had a pregnancy scare recently. I was symptom spotting so much & spent way too much on tests lol. My periods are normally 7 days. This is my first cycle off of birth control and it was only 4-5 days but there was definitely red blood and some clots. I cramped a lot the first day but didn’t feel anything for the rest. I normally cramp the whole time. I took a test 6 days after I stopped bleeding and it was a negative but I also used a blue dye. I would’ve been almost 5 weeks by then so there would’ve been a definitive line right? I’m still scared for some reason! What can I do to calm my nerves lol.
