Help! Any advice?

My cycles are typically 25-26 days long. I tend to ovulate (surge is detected) on cycle day 14,15, or 16 each month. This month I bbt and ovulation was confirmed. I use the clearblue advanced and detected a surge (solid smile face) on Nov 13; Easy strip confirmed this. The following day (Nov 14) the easy strip test line was darker than the day before and then was negative by 5pm on Nov 15th.

I think I have a shorter luteal phase. I’ve only been monitoring for 3 cycles. I’m 34 and I’ve been taking prenatal vitamins since August. Never been on the pill.

Any thoughts about pregnancy odds this month? If this isn’t my month, any suggestions or advice for next month? I appreciate your support!! Good luck to everyone!!!!
