Brown discharge??

Shi

Okay ladies, so my cycles are irregular. Lasting anywhere from 20 to 45 day cycles..

I am currently on cycle day 49..

Cycle day 46 and 47 I had a tiny pink tint when I wiped in the morning.

Tested on cycle day 46 and it was negative.

Cycle day 48 and 49, brown stringy/stretchy discharge..

Have been having pregnancy like symptoms for about 2 1/2 to 3 weeks...

What do yall think it could be?
