Help please!!

Sarah • 20🤗 wife💍1/24/18💙 4/21/19💜 baby #3 due 4/14/20💛

My ovulation was supposed to be Sunday (the 21st). Last period started on the 9th (first pp period; my daughter is 3 months). We aren't actively trying, so I haven't been tracking in depth. Anyway, we had sex the 17th (condom), the 19th, 23rd, and 24th (pull out), and the 22nd (nothing). Thursday and Friday, I had a tiny bit of spotting and quite a bit of discharge. Just now, when I went to the bathroom, this was there the first time I wiped. Second time there was no blood and just a lot of kinda sticky/slimy discharge, I guess. I've been kinda moody and crampy and somewhat nauseous, but I couldn't be having pregnancy symptoms already, could I?! Please help!
