Low Morphology 3%

I am 5 days post 5 days transfer and I'm bleeding like a period:dark red blood, cramps and clot.

This is my 2nd ivf cycle which is looking like a failure..Im still holding on to 20% hope/desparation/denial.

Last year was only egg on day 5 which ended in early miscarriage. On my 2nd cycle, we had 4 eggs on day 5. I put back one but the other 3 stopped growing on 6 and wasn't frozen.

Hubby had 2% morphology. Started taking supplements and has been a consistent 9%.

Idk if this cycle failed because of the hurricane in Mexico. Basically on retrival day, there was a hurricane. So I only did my retrival and froze the eggs. The clinic couldnt fertilise the eggs the same day so they did the next day when the city turned back on the power. This one day caused hubby to be on day 5 of abstinence. Not sure why but apparently he wanted to give 4 day old sperm but that one day put it at 5. The paper said he 3% morphology that day.

How many tries did it take with low morphology?

Any advice on what helped?
