I am a 30-year-old woman with a weight of 75 kg, height of 5 feet 5 inches, and my husband's age is 34. We got married two years ago and still have no child. I have been trying to conceive for the past one year. My cycle days average between 32 to 34. Last year, I missed my periods, but my urine test was negative. I had lower backache, tender breasts, and feelings of vomiting, but later on, I got my periods after 43 days.
Currently, this month also, I had the same symptoms. At the start of this month, my urine pregnancy test at home was negative. I am tracking basal temperature for ovulation days, cycle days, and BBT graph with corresponding days. The temperature image is also attached below.
Please guide what could be the probable cause of these happenings. Should I approach an infertility specialist or a gynecologist for my symptoms?
