Needing Some Advice and success stories

I’ve read so many different things about it and my nervous are getting the best of me.

I also have a few questions if anyone can answer them.

BACK STORY I am 24 Years old. Was Not trying but not preventing for almost 5 years. Actively Temping Testing and Really Trying for 2 years.

I have tried preseed for 3 months with no success.

My Doctor did do a great job explaining everything to me I was prescribed 50 mg take cycle days 3-7 and have Sex days 10-18 BUT I have seen several people say their doctor told them no sex After Day 18 my doctor never mentioned not having sex after any certain time do I need to not have sex after that day or is it fine?

The Horror stories on the side affects I think is what has my nervous shot. I have literally read stories where people were close to divorce and/or a mental breakdown over the mood swings. Is there anyway for me to lesson the affects I may get from it?
