OHSS or Period

[2020F]

Hi Everyone, I had my 2nd cycle last month which ended up being a freeze all due to increased progesterone and chance of OHSS. I am awaiting my 2nd bleed so I can start my frozen transfer. However my stomach is very bloated and tender in parts, has anyone else experienced this is it normal?

My egg collection date was the 27th of July could this still be OHSS or symptom of period coming?
