Took my period a week ago and since it started i have had nausea and frequent urination. Im now finished period and nausea still here. I rang doc and he thinks urine infection but have no stinging. Im also perimenopausal and wondered whether it was hormonal. Thyroid is stable. Had low calcium and vit d was treated with calchichew and took extra vit d myself. B12 is at 2000 since supplementing. Does anyone know why this nausea is persisting?
