Prolonged period issue!! Need guidance!!

I did abortion on 2023.. It wasnt surgical, it was medical..

It went all well..

After 3 months of abortion, when i got my period, it didn't stop for more than 21 days..

I visited the same hospital and they ran several tests.. Everything was fine so they have me hormonal tablets.. No issues after that..

But 1 month before i got same issue.. Period didnt stop for more than 2 week.. I went to new hospital as the doctor that treated me before had permanently shifted abroad..

I bought all my previous test results and new gyno doctor ran CBC, Urine/RE(HI), Culture and sensitivity(HI), Pregnancy test, LS/FSH, prolactin test, t3t4 tsh, and USG tests..

Result was all normal but there was small bubble like cyst which was not serious.. Gyno told me its not big issue and sometimes that cyst goes on its own but suggested me take video xray every 3 months, just to be normal..They gave me tablets to stop period and thats it..

Now,. Its another month and same issue has repeated..

Bleeding was light at first, then light spotting and after 2 weeks, boom, heavy bleeding..

Point to be noted.:

I have gained weight( age 25, height:4"11, weight = 73 kg)..

I think weight gain has played huge role in all this as i was just 52-54 kg in 2023..

But still i m very scared..
