Is this maybe it? Warning- possible tmi photo

Ladies, let me start out by saying possible TMI picture, as I said in the title. Also, I don't think I'm pregnant because I'm negative about this, I'm tired of getting excited and being sad. So I decided to ask you all instead of just overthinking it to myself.

Here's the info--

-My period was Dec 2-5th

-According to Glow, my fertile week was the 15th-21st, with Ovulation the 20th

-I had unprotected sex on these days-

2nd, 9th, 10th, 15th, 16th, 19th, 21st, 22nd, 24th, 25th, and the 28th.

-since the 26th I have felt off. I have little appetite, I feel nauseated, I'm tired, lightheaded, tender breasts, I'm not sleeping well. I just don't feel normal. And also I've he stomach issues each morning since, mostly runny bathroom issues.

-this morning (29th) I went to the bathroom and had some pink when I wiped, that looked a little thick, but definitely not period blood. I got up to look and there was a bit more pinkish material/tissue in the toilet.

-my period is due January 3rd, according to Glow(which seems to usually be a day or so off).

At this point ladies I'm just wanting your opinions. The photos show the pink wipe after using the restroom, and inside my toilet the pinkish material/tissue. Now ladies, I had just woken up so of course there is other bathroom matter in my toilet. I did my best to get only the pink, but a girl's gotta go you know? Lol
