Need advice before I drive myself insane!

My husband and I have been TTC for 8 months now. Ever since I got off birth control my periods have been irregular and very heavy except for the last two months. I had started taking Maca root two months ago and they have helped regulate my periods and hormones. Anyway, my cycles are usually 32-35 days and right now I’m on CD 41, 22 DPO and 7 days late. Every test is negative. We were just on vacation last week when my period was due so I wonder if that’s what made it not come? Or could I be pregnant and just need to wait a few more days to test? I’ve never missed a period due to traveling because I tend to always get my period on vacation 🙄 and the only other time I’ve skipped a period was when I was on BC. Any advice?
