Think I may have blood clot from BC, should I go to doc?

I switched birth control from DEPO to a low hormonal pill, but my body is still adjusting 6 months in. I have long periods of spotting and long periods of no cycle and it's caused my B12 to go down a lot (it was already never that high to begin with).

I feel I saw my results come back that I was at risk of clotting, which makes sense given the situation. While I can't find those exact words in my results I did look into lower test results regarding my blood and did see that it signified an increase chance of clotting.

I had a normal day today, but woke up again at 4 am (for some reason). While listening to music I realized I had a full pain in my knee. Well, the side of my knee area. It's on and off but it's a dull throbbing feeling. I figured it would go away as I normally have restless legs during sleep (usually my right leg which is conveniently the leg I'm having issues with).

I feel like I've had this kind of pain before, I'm uncertain but I think so. But with this birth control thing, my test results, and with me having to start taking liquid B12, I'm starting to wonder if I should be concerned. I have a pretty sedentary life style (office job, gamer, like to drive), so there's a lot of things that I feel could be compounding my worry. I've since taken an Advil, I hope I didn't make things worse, the discomfort (dull and slightly annoying) is starting to go down a little. Nothing swollen, no heat, some relief with certain leg movements.

Should I go to a doctor? Am I overreacting? I really don't want to go, I have a long drive in the morning to an event I've been looking forward to, but idunno now. I am also in my mid 20's, so I'm younger. Sorry for the long post, pls help?
