TTC and CONFUSED... HELP!

Hey guys. Well... for starters, my periods have always been irregular and I’m assuming I ovulate late. In May my cycle was the 4th-8th. I had sex on the 11th,18th,20th and the 26th. On the 19th i took a opk and got a positive. I found out I was pregnant June 2nd and had a miscarriage on June 16th. I was 6weeks....Ish. I bled for a awhile after the miscarriage and didn’t get my next cycle until July 21st and it lasted until August 2nd. In August, I got two periods that month (8/10-8/14 and 8/27-8/30). In September my cycle was 9/16-9/23. I had sex on the 29th and on October 4th (CD19) at 7am and 7pm I got a positive opk. I didn’t test on the 3rd so I’m not sure if that test would have been positive or not but I did test on the 5th and by that morning the test line was faint and by that evening the opk test was negative. I have 3 period tracking apps (they almost never lead me wrong) and two said my period was supposed to start on the 10th and the other said 11th.... it’s the 12th now, so I’m late a day or two. Over these past few days I’ve been feeling kinda funny. I’m bloated, no period cramps but light spasms cramps that feel like tickling on the inside or knocking maybe. I’ve been nauseous here and there with heartburn, diarrhea and a good amount of white lotion CM, (TMI) but it’s enough for me to go to the bathroom to while because it feels like it’s dripping out of me. I’ve taken a pregnancy test or three and they’ve all been negative. Am I tripping and going crazy??! Any advice? Any facts you guys can throw out there at me? Help!
