**Implantation Question**

I feel like yesterday was the day I had implantation, but still unsure. I had left side lower twinges/pulling all throughout the day. I definitely noticed it, but never was painful. I also yawned ALL day yesterday and I even had a well rested sleep the night before. I also had a headache that wouldn’t go away. Before bed I noticed a few seconds of lightning bolt sensations in my left boob. I woke up this morning feeling like I had a workout - body feels sore and especially the left sided spot that I felt the twinges & tugging yesterday feels sore. I’m already getting a slight headache this morning and I usually never get headaches. Does this sound like implantation?
