Anyone experience this?

So back in

April I had a period from the 14-18th

May NO PERIOD

June NO PERIOD

July the 10th I took a test which was a very slight positive.

July 11-15th heavy bleed with two days were spotting (possible miscarriage)

But then I spotted

August 24-28th full on spotting???

Took a test this morning as the last week I've felt flutters thinking 🤔 have I feel pregnant in April or around that time as I wouldn't be feel.ing movement the movement, and flutters, are on the left-hand side and only notice when im resting or sitting down im so confused.

I'm tired, have a major back pain, dizzy, have sickness feeling a few weeks ago. And I feel im feeling something is there but why is the test negative 🙈
