13 DPO pls help

soo this is my cycle, Me and hubby are hoping this is our month so we've done it alot this month, multiple sessions multiple times and never does the pulling out method, always stays in, so I took a preg test on Saturday morning and it came out as a BFN, I had drank alot of water the night before, ( I've been super thirsty ever since ovulation ) so I was thinking that was why it cane out like that.. but I didnt test today was thinking of retesting tomorrow, I usually get super bad cramps two nights before period and I didn't get any, my cycle is pretty regular 30-31 day's, I just was curious of your opinions, so you think the BFN was a negative or couldve been a false? I havent really had symptoms, I had mild pms/like cramps 6dpo, and super sore boobs about 8-10 Dpo where I couldn't even touch them and now my nipples are sore..

Please share opinions ! 😊
