So my last pregnancy only took because I took prometrium. I took it from 3DPO until I was 12 weeks... I am fairly certain that I O'd on Friday. I got a positive OPK (and one the day before) and I had O pains and my temped dipped like a whole degree. The only issue is that my temp didn't go up past my original temps, though it did rise ( and rise again today...) but I think that fertility friend will tell me I O'd on Saturday... Should I start prometrium on Monday or Tuesday?

I am not 100% confident in my temps since they are not taken the smae time every day and are taken after 1-3 hours of sleep.....
