B6 and delayed period

So I started taking b6 this month to hopefully lengthen my luteal phase... and that it did, kind of. I’ve read aaall over that b6 will delay periods, has anyone else experienced that? I have a 28 day cycle. I am currently on day 30 with no real period. I’ve been spotting for the last 5 days (started on 8 DPO)... it has been aaaall over the place- sometimes pink, sometimes brown, then BRIGHT red (I thought my period for sure came but NOPE, literally stopped by the time i was done wiping), back to brown. And now it’s still brown and no REAL period in sight. I had cramps ever since I started spotting. My temp first spiked down on Sunday when I started spotting, and this morning it spiked down even farther back down to the beginning of my cycle so I’m thinking maybe the b6 is just delaying it possibly, and since I had such a low spike in the temp maybe my period will (hopefully) be here by tomorrow. I’m getting really sick of feeling like this entire week there is something coming out of me at some point during the day lol
