worried so much😞

I got my Af this month, however it was very light... since one year now I have been experiencing very light bleeding that lasts only for one day.. my gyno thinks this is not a problem... but I am very much worried that this may be the cause for me not being able to concieve.. should I really be concerned or is this not a problem.. does anyone else have scanty periods?? What did u do..?? Plz reply...
Have done everything to get my bleeding to normal, don't know what else to do.. 🙁🙁
