9DPO - help! 五

So I have a short luteal phase and my period was due yesterday. Still have no signs of AF and temps are at the 98 mark. Had a huge drop on 7DPO based on my bbt charts. Been feeling okay minus major gas pains in my stomach. This is also not with FMU (had to pee at 4am but couldnt resist.) line showed up quickly and got redder as the minutes passed. Could very well be an indent, I havent used these before. let me know!!
