Frustrated

I go in for my second ultrasound on May 8th, which is a Thursday, and it is cycle day 12 for me – if I am ready to go then they will trigger me and I will have the IUI on Friday the 9th – cycle day 13. But if I am not ready to go – I know they are going to push me to Monday – which will be cycle day 16 and I really think it will be too late – this happened with the last cycle – my O time always seems to end up on the weekend – I think my O will actually be on Saturday the 14th – I do not know what to do – in a perfect world – I will be ready to go by the 8th in the am but we do not live in a perfect world and I have a feeling this IUI is going to be all messed up like last time – I just want to cry – why can’t my Re’s office be open on the weekends – this is ridiculous.
