Any idea why it looks like this. Tmi pictures.

Please help, i posted it in another group but got no replies. :(

But, Tuesday when when i wiped i noticed blood, but only a little bit & that was the end of it. Two days went by and no blood, nothing. Friday, it was pinkish red. Then while my husband and i were at my parents dropping my daughter off last night (still friday) i went to the bathroom and when i wiped it was completely pink. After we got home i went to the bathroom and it looked pink with maybe orange-yellowish. I have no clue.... 😱😬

FACTS: i do have cramping and feeling super comfortable lately. We have been ttc for over a year. I have to take progestrone pills (for 10 days) to "jumpstart" my period because it is EXTREMELY irregular. But i have been on it since about June 2015. And it never gave me pink or the colors in the picture before. While on that, i took letrozole on days 5,6,7,8 & 9. (Doctors order). I am hoping it has to do with pregnancy since we have been trying,but of not i think i should be concerned, am i right?

The picture that is attached is from last night when we got home around maybe 9-9:30pm.
