Ultra & internal scan for OHSS clomid in 2 weeks

Sophie

When I have my scan in 2 weeks glow has calculated it’s the time I should have my period or BFP.

1. Could the ultra sound pick up anything at a possible BFP 5 week 4 day?

2. If I do come on is it a good idea to continue clomid if I’ve suffered OHSS from second round of clomid at 50mg? Could that ease on a third cycle or just get worse?
