Help - long menstrual cycle and day of bleeding in middle

I’m 30 years old and have been with my husband for nearly 10. Several months ago, on my 30 birthday we decided to start TTC. I stopped taking my BC and downloaded Glow to start tracking my cycle for pretty much the first time ever. Yes I probably should have before but never thought it was needed.

Anyway, I am realizing my cycle is very long and abnormal from the research I’ve done and I’m starting to worry and was looking for more knowledgeable advice... I stopped my pill after one of my periods in August. Then got a period only two weeks later in Sept which I wrote off to being a random side affect to stopping BC. My next cycle was ok at 33 days and made me realize my OV days Glow guessed were off!!

The next cycle is where things get off. It was 38 days, where I started having brown spotting for FOUR days before getting my actual period. I falsely took it as implantation bleeding before realizing it wouldn’t last that long and test BFN.

This month, I had one day of random regular period bleeding about two weeks into my cycle but otherwise (which is NOT usual for me), I’m currently on day 38 with no signs of even spotting and again testing negative. I’m getting worried and wondering if I’m over reacting? Is this normal? Is it worth seeing my doctor? Has anyone dealt with anything like this before? Could it still be my body adjusting to being off BC? Like I mentioned I’m sadly new to tracking and TTC so any advice is appreciated.
