Early Symptoms?

El
Hi! I am 33 & TTC # 1 Cycle 8. Have had really bad gas pains in my chest/abdomen. Started 1 DPO. This morning, BBT dropped but I tested several minutes earlier than I usually do. Left side pelvic pain/cramping. Feel bloated. My nipples feel sensitive (sorry if TMI). Thoughts? I am 4 DPO now. TIA!
