1st round of clomid and follow up scan

I did my first round of clomid last week (21-25 dec d2-d5). On d11 which is 28th dec, i went for a follow up scan and found out my follicle is the size of 8mm (which my gynae said it’s a bit small, and should be at least 10mm above). My gynae advised me to go for a follow up scan at d11, but i wasn’t able to because i went back to my hometown and it’s a bit hard to find a fertility clinic or any other clicic that can do transvaginal scan.

My question is, should i do a follow up scan on d16? Just to check on the follicles and lining? Or should i just bd and just wait for the upt result?

P/s: i started bd on d11, and probably will bd until d19 (once every 2days) or until i feel the cramp. I know i should’ve do opks but i totally forgot to bring back the opks to my hometown, and only will be back on sunday (3rd jan - d15).
