DPO symptoms??

So I am 7 dpo right now, but had symptoms since 3 dpo (I know it's early but still happened). Anyways, my symptoms were cramping on and off every day since then, had nausea and dizziness 2x at 4 and 5 dpo. Sides of boobs are sore like in the armpit area and sensitive nipples. CM is kind of creamy/watery but light. Headaches almost everyday as well but that's not unusual for me. Past 2 days my cervix has been high and closed but between soft and firm. Today i have a stuffy nose so i think im getting sick..bbt went way down for 2 days and today went up a little. Am I going crazy!? What were yall symptoms??
