10 dpo bleeding?

Hi, sorry if tmi. But I woke up in the middle of the night to go to the toilet and when I wiped there was blood. It’s like 4 whole days before my actual period is due. So this morning there was a gush of more blood and I thought for sure my period has started. But for the last hour there’s been hardly any blood at all??

Has anyone else ever experienced this and what was the outcome? I’m a bit impatient but don’t want to test yet.

Ladies - the blood is like bright red so I’m a bit skeptical. Just want to see what happens today/tomorrow. What’s the longest implantation bleeding can last? I really hope it is, we’ve been trying for 4 years and I had hsg few weeks ago and everything came back ok
