I had my periods regularly for 3 months continuosly and i m anemic and by taking iron tablets it became normal periods and after that by this may i did'nt get my periods. And this june i started from 7th but not regular bleeding it was half proper and till date its spotting daily. Is this normal or need to concern. And i had unprotected sex before my periods in march, got my regular periods in april (next month) too but when i missed my periods this may month i am little worried. but checking by kit i got negative and  after this june its not regular one with spotting,this is my frirst time having spotting after periods. Please do help me with right answer.
