Irregular bleeding. Spotting. pl he!

From beginning I had irregular bleeding, which prolong to nearly one month or even more. After diagnosing problem was minor pcod. Ovulation problem. But had a girl baby with having fertil tablet. Cervical mouth was wide so lost first baby at 4.5 months. Then after having tied cervical , delivered baby with c- section at the age of 28. Even after delivery my bleeding was never regular. But six years back diagnosed with thyroid problem. So took medicine for 3 months. Simultaneously had accupuncture treatment. Reason not known but bleeding started stopping by 5_6 days. But not regular. I can find myself ovulating as used to face pain for 7-8 hrs. Then after ovulation on 10 the day used to have bleeding. But suddenly at the age of 39 had ruptured ectopic pregnancy. Undergone laparoscopic surgery. Now I am 42, since last six months again I had irregular heavy periods. Used to get spotting in between. And bleeding wold continue for nearly 10-15 days. Even after that will have spotting. Pl he
