So I had a wave like contraction type ache for like 30 seconds yesterday followed by some pinching later on in the day. I've had a few pinches today too then had this when I wiped. Is this implantation? I think I'm around 12/13dpo. The first is what I got around 4pm then when I went to the toilet at 6pm had the creamier brown discharge but nothing on the liner and nothing since.
