CLOMID HELP

HELP...

so I am on clomid to assist with conception... I am now on cycle day 29 with 3 follicles 1 at 15mm 1 at 18mm and one at 24mm... they expected me to ovulate by now however I haven't back for scans again Monday (I have had them every other day for 3 weeks now) please tell me I aren't the only one... can I still ovulate my period would normally be due in 5 days and these follicles are still growing. Doc wants to see me Monday if still not ovulate then going to change medication for next month... hope this makes sense xxxx
