My wife had menorrhagia (extremely heavy periods that lasted a week) and extreme lethargy. And restless legs. Not only did her doctor not get her bloods checked, he didn't care about the heavy periods and said (about heavy periods), "go on the pill, and see a shrink" (because presumably he thought she was a hypochondriac or depressed, because she came back several times to see if he could do anything about it). He finally got her iron and B12 checked, and since they were both on the lowest end of the "Ok" range, he didn't do anything further.

It took 2 doctor changes and a lot of goggling to realise that her menorrhagia had a cause, but that she's need scans to prove she might have uterine fibroids. It took 2 procedures to correct them. Once all that was done and she got iron + B12 injections, and got her life back.

On a forum she talked to other women who were left to deal with fibroids for up to a decade because their doctors would just sigh and say, "Yes, women's problems. This is normal. Go on the pill". Unfortunately the fibroids grow so large that there is sometimes no option but a full hysterectomy. This is a common story.

I completely agree, you need to do your own due diligence these days.
