Ovidrel, iui, omg I’m clueless 😩😩

Hi guys so after 4.5 years of infertility we are finally gonna try something else. IUI is our first step....I know I’m over thinking everything but .......sigh!

So when you’re testing out the ovidrel how do you know you’re system no longer has it when you do the hpt? I read some women will test it out but if it’s going to show positive like you’re pregnant then how do you know for sure you’re not? Do you have to wait until you get a negative first and then test to see if you’ll get a positive after?

Also at what point do you start using those opks? Tonight is the last night of the clomid cd4-cd7 do I start using the opks tonight or tomorrow?

And to check your temperature do you check at a particular time of the day and do you start checking on a particular CD? I’ve read a lot on here but I’ve never really understood the things I’m asking about...

I’m trying to increase my iui chances as much as possible.

Thank you !!!
