Retest or dr?

My periods are very regular and always have been. My husband and I have been (officially) TTC for a year this past June. We went to a specialist in May that said all was well with everything since I just turned 36. My periods have always been 3-4 days with a history of fibroids & endometriosis in my early 20s/late teens. The few cysts/fibroids I had over the years have dissolved themselves and in the most recent ultrasound from June everything was clear. I just had an HSG done in July to make sure there were no blockages and all is clear.

I just had my period on the 21st and it was weird. If I have any cramping at all it’s usually day 1, but this time, it hit like a truck on the 22nd but by the end of the day, my period was done. I spotted lightly on the 23rd but that was it.

I took a pregnancy test this morning and it was negative. I’ve been nauseous/dizzy off/on and have had some cramping/pressure since Saturday.

Would you recommend retesting? And if so when?

Also I did it with a blue dye test and I’ve heard mixed reviews on those.
