This is embarrassing but I need some kind of peace of mind

Barb
Normally I wouldn't post up such pictures that are tmi n embarrassing for me to post but I need some piece of mind, I googled it n read that it's pretty normal to have but my doc appointment isn't until the 2nd week of September so I just want to ease my thoughts until then, I've had a papsmear n test done for std's n crap (u know those routine test they do just in case) n everything came out good n this doesn't happen everyday just every now n then so far I've had some once yesterday n once today (I dunno if it's due to having sex or not because in the past I had it a day I had sex also) so far I've had this discharge on the toilet paper when I wiped after I peed (the amount of it varies) maybe 4 or 5 times total, according to articles I've read it's normal. I have a sonogram/ultra sound tomorrow n I know seeing the baby good will definitely make me feel more at ease. Sorry for the images it's just easier to show instead of discribing oh n there's no odor with it, it doesn't burn or sting when I pee n I don't itch down there n I'm not swollen, inflamed or red down there 
These pics are on different days the most recent is the very 1st one
