Hi guys

Here is my story. (its pretty short )
Been on the pill for about 10 years.
Went off the pill almost 3 weeks ago. About 5 days after I went off the pill I got my period. Lasted about 5-6 days as per normal when i was on the pill. Finished just over 1 weeks ago.
Been trying since then even though it wasnt in the right cycle time (to my knowledge) and now today (about 8 days since my period finished) I have a small amount of bleeding which isnt normal for me (although i have been on the pill for a long time so i dont really know what is normal i guess).

Is it possible that I could be pregnant or is this just my body getting used to being off the pill and finding its own cycle? Just seems strange that i would get a period and then 8 days later have another 1. strange.
Also, yesterday i actually did a pregnany test just out of curiosity even though id had no signs at all and it was negative.
Would it take longer to show if it was? What could this new bleeding be?
Please Help.. first timer and a bit freaked but hoping so bad!

Thanks
