TTC (Trying To Conceive) With PMDD

Boy (or girl), who knew this TTC business would be so tricky, right? 14 Months after I went off Yaz, two ovarian cysts, an out-of-state move and much relationship rehab later, here we are actively trying. I'm currently 7DPO (days past ovulation) and I was doing really well not being hyper-focused on potential symptoms... until yesterday. I experienced some spotting that is quite abnormal for me. Dark brownish-red in color and scant amounts dried in my underwear when I went to the bathroom. Pretty much nothing when I wipe or for the rest of the night. Today, some creamy light tan CM (cervical mucus/discharge). I also started having mild lower pelvic and lower back achiness yesterday which subsided by bedtime and picked back up today before I noticed today's CM... just like yesterday's pain came before the spotting. I'm crossing my fingers it could be implantation and trying to hold out until at least 9dpo, but hopefully 12dpo to test. There's no way I'm getting to 14dpo this cycle. Also, a slight drop in my temp yesterday and back up today. Here's to hoping! If I am preggers, it would be quite interesting, because I've been extra tired for several days now and writing it off as too early, but we all know how hyper-sensitive PMDD makes us! eek! I hope this is our month.
