Missed period with bfn

Hey everyone,

My husband and I have been ttc for over a year. He has mfi and we’re working with a fertility team. First step will be medicated IUI and we’re on the wait list for IVF. Things have been on hold though until my medical team clears me for pregnancy because my Crohn’s disease is not in remission.

Anyways as the title said I’m at cycle day 45 (normal for me 27-38). I tested last week and this morning but both bfn. It’s possible that it’s because my Crohn’s but I’ve never missed one before and have been much sicker with my disease.

What do you typically do in this situation? Just hold off and hope it shows up next month? Should I bother touching base with my doctor?

Note: I often don’t ovulate (which is why we’ll do medicated IUI) but on those cycles my period is push off by 5-6 days and continues as normal, I’ve never been this late before.
