So i was due on today woke up and wiped and a small smear of pink blood, popped a towel on. Went to the toilet again later on super super wet but only a very small amount of blood. Came back to the toilet again and it’s super wet again and only brownish colour with a small streak of red. Could this be implantation or is this my period? I usually start really heavy so very odd for me... i also have super bad lower back pain and a heavy feeling in uterus ....

Any comments would be helpful
