Period was January 11-13

I’ve had unprotected sex various days in January

Possible implantation bleeding feb. 4 &5 with just one “wipe” of ib and the second day it did it it turned a brown color only lasting about 2 hours (wiping).

I’ve been testing everyday since with all negatives!

Period suppose to start feb 11th and hasn’t.

I just been having light cramps each day and a queasy feeling in my stomach (almost like morning sickness but only

Lasting the evening for a few hours)

Is it too early for a bfp?

What do you ladies think?
