Curious. Any advice helps.

So on July 17th at around 2 or 3 AM my boyfriend and I had sex. I woke up the next morning and at about noon I took and ovulation test that was positive. So fast forward to 5 DPO and I started having cramps, gas, and felt like I was bleeding. But I was just very wet for some reason. I do take my temp but not with bbt just regular. I know bbt is better but this is what I have. At 5 DPO my temp was 99.1, 6 DPO was at 98.5, and today at 7 DPO I'm back up to 99.3. My temp is usually around  96-97 area around this time. So could this be possible implantation? Thanks for your help!💕💕
