Help please 🙈🙈

Hi I'm wondering if anyone can help me 

i took preg test end of last month as I had really white discharge and it was pos line was so faint but I guess a line is a line... so I took a clear blue one and it said not preg🙈

bled on the 16th of Aug at first it was so light then got heavy,stopped bleeding on 18th but woke up with really dark brown on my pad (sorry for to much information) so I took a preg test today and the lines are yet again so faint but I've got really achy legs,get really bad head aches and so upset sometimes.. I'm wondering if anyine else has been are had these and will be able to help me... Thanks for reading 😀Xxx
