I NEED ADVICE!! PLEASE!!!!

(LONG READ. PLEASE READ IT THO) This is my third month TTC (trying to conceive) and I ovulated real early this month! But I also have irregular cycles so. And this is the first month I had O (ovulation) bleeding. Fun! BD'd the 1st,2nd,3rd, and tried the 5th but didn't finish(tmi sorry!) was very fertile the 3rd and 4th due to lots of EWCM. Ovulated the 7th, I think. Could've O'd the 6th too. I've been having the weirdest cramps since the 11th and have now been experiencing headaches and dizziness! Headaches in TWW are normal for me, dizziness and cramping? Not so much. I've never experienced PMS before but I'm entirely sure that it would be too early for that. The pain I felt on the 11th was abdominal and just-weird. It would go from sharp kind of poking? To like a pinching feeling? It lasted literally 13 hours. I also have insomnia but for three days straight I was unable to fall asleep nearly at all! Usually I can get to sleep 20-30 mins no problem. So that's weird. For a couple days I've also been checking my CP and i'll get these globs of EWCM-like stuff? Yesterday it was yellowish and like snot? I know this sounds like a lot of symptoms already and like I'm symptom spotting but I'm not done. I've also had tender and sore nipples since the 13th and my nipples-usually don't have feeling? So then I checked and they were getting red and then they were cracked??? I've never had cracked nipples and I've been putting ointment on them to heal but they're still sensitive and still feel like they are being pinched occasionally?? So then strangest thing of all! Woke up this morning with brown CM in undies and when I wiped. Never had brown before so I freaked out. It was very little. Some sized amount. Every time I wipe after going to the restroom it is also slightly brown. Put on a pad just incase and only had maybe a drop or two more in the past 10 hours. No cramps today either but indigestion and sore nipples.
