It's best for you if you don't immediately dive into the manga, you'll just burn yourself out. Do as you said and come back in a couple of months.
>On a side note, what are your thoughts on OVAs like Rei, Kira, Outbreak and Nekogoroshi etc? Are they worth checking out?
They all are to an extent. The middle three episodes of Rei are the Saikoroshi arc which is set after the series and were pretty much universally seen as canon prior to Sotsugyou (and should still be seen as so considering how much of a trashfire it was). Kira is dumb noncanon fanservice stuff but a lot of people love the final episode so watch that at least. Nekogoroshi is a standalone episode which plays into the mystery of Hinamizawa and is very good for what it is. Outbreak is fun but trash and completely not canon.
tl;dr Nekogoroshi, Rei 2-4 and Kira 5 are essential, but everything else is at least watchable.
