Is a 6+ week losing streak on 50/50s normal?

I've lost every single 50/50 since at least the Centaureissi re-run (6 weeks ago). It've might actually started earlier than that during the Vector banner, but I wasn't keep track back then.

Is this normal? After losing two more 50/50s the past 2 days, I'm starting to feel this isn't even 50/50 but a guaranteed loss.
