Needing advice please!

So I've been getting this for the past few days, tingling nipples and metallic tastes with sensitivity nipples, I'm also due on in 12 days could this be possible implantation bleeding? I had the implant out in November and I've only had one bleed since then and came off about a week and a half ago, so not sure when I ovulated etc as i could of ovulated sooner being very light period, I wouldn't even call it a period really! It's just I'm getting the same symptoms I did with my first and fell very quick with her!
