I have noticed the past couple of months my period getting lighter and shorter but brushed it of thinking it would return to normal but the past 2 cycles it only lasted two days one being spotting then light bleeding by the 3rd day it was completely gone

Af started today and it's so light I know for a fact it's going to the same tomorrow ( same thing happened couple months back) I'm actually very worried now because this is not normal and on top of that I have been ttc a long time (5+ years)but gave ourselves a break for a couple of months but now that we are trying again it seems we now have another problem

Does anyone have any advice?

Some one told me maybe my uterine lining maybe to thin ? I got some raspberry leaf tea today apparently it helps thicken it up

Sorry for the long post I'm just worried
