Is this normal?

So I've never really had what I would consider a heavy period, I could usually get away with tampax light tampons and a panty liner (changing every 1.5-2 hours) but the past 3 months I've been out of tampons (no better excuse that terrible memory at the store and pure laziness when I get AF and remember💁) so I've been using just panty liners (changing every 45 min - to 1 hour) and it seems to be totally fine... is this TOO light of a period or is it normal? (Also been TTC since November with no luck, its starting to freak me out, am I broken 😭😭)
