When to start Clomid?

Joanne

I have regular monthly cycles but my hubby has low motility. Consultant has said to try Clomid with ovetrille injection after a scan. My question is by looking at my calendar if I start Clomid day 2 for 5 days. Will I ovulate about the same time as I usually do or will it be earlier? Because I am going away with my mum from the 28th for the long weekend as it's mothers day but this is during my fertile window or shall I not start Clomid this cycle and wait for the next? I hope this makes sense.
