Should I see my OBGYN?

So I'm 25 and already have 2 healthy kids. Me and my partner have been trying to conceive since I stopped taking the depo shot in Feb 2019. I finally got a BFP late Aug 2020, but unfortunately I miscarried a week later. It took 3 weeks after for my HCG levels to go back down to 0 (my obgyn was taking blood every 2 days because my HCG levels kept going up and down). My partner and I decided to keep trying. Now its March 2021 and I still havent been able to get pregnant again. Im starting to get discouraged and feeling like there might be something wrong with me.. Anyone have any advise? TIA
