Missed period/ovary pain

La

I’m on day 5 missed period, been TTC for months! Anyway, I’ve been getting this pain on my right ovary, kinda like a cramp, here and there not so often but a couple of times. Im usually regular, except last month where I was a week late but it was most likely due to stress. I don’t think I have a cyst because I don’t have any other symptoms. I also had really watery discharge the first day of my missed period. Could I be pregnant or am I just tripping?
