BFP after implantation bleeding

Posting this to give ladies some hope!

So I was due to have my period on 20/12 (28 day cycle) which was a Wednesday. Tuesday I felt like my period was coming.. nothing. This feeling happened until Friday, I put on a pad before I slept cos I was sureeeee it was coming. Got home Sat morning from a night shift (4 days late for period) and had blood.

Thought I was out, had a shower and cried. Put on a pad and through that day only had lil drops of pink blood… mostly on the tissue. But my periods are usually painful and super heavy so this was odd. Also had PAINFUL gas like feelings going up my back. For the next 3 days, bleeding stayed super light and it was weirdddddd! Today, was day 3, woke up with no blood. Decided to take a test and came up in 3 seconds! 😳 another thing was my boobs usually stop hurting the first day of my period but they didn’t 🤷🏾‍♀️
