TTC How many times can I do it a day?

Ana

I began ovulating on Saturday I had sex that day as well as Monday and today usually our times is at midnight when we usually go to bed today is one of the days where I have a high chance of pregnancy (27%) and we did it at 12 am I wanted to do a second round today before midnight but my husband is not feeling well and I don’t want to pressure him tomorrow I have a high chance which is a 33% so we were planning on doing it tomorrow as well. I shouldn’t stress about doing it too much or should I? Also, does the amount of time matter as well in how long we’re doing it?
