Implantation bleeding...how to know?

More than anything I just need to share my thoughts with someone!

I am now on day 34 of my cycle (roughly 20dpo) but no af. My cycle length is a bit irregular when off the pill so nothing unusual there.

For 4 days I've had spotting, 2 days very light, 2 days light. Keep thinking must be starting af then nothing, clear wipes this evening still. This is not usual for me, when I start I start.

3 days ago tested negative. Will try again in a couple of days if no clear sign af has begun properly.

I know I'll either start or I won't... but am sat here wondering if what I'm experiencing is implantation? Thought that only lasted a day or two if at all but other users on forums suggest it can last for longer.

Anyone care to weigh in?

 

Still no sign of af, spotting almost gone entirely. Tested negative with a simple clear blue this morning. Confused! Will probably try again in a few days. You're right, maybe I should go to the doctors at the end of the week if I'm still not sure. Thanks ladies!
