Hi, just need someone more experienced with this. First month using these. It seems my peak was on the 21st, but I didn’t have sex that day or the day after. If I understood correctly after your peak or surge, it takes between 12 and 36 hours to ovulate, would this be correct? And if so, could I get pregnant if I had sex on the day before my peak? I’m not sure when exactly I ovulated, no one can really tell unless you go to a doctor, but on the 21st I had twinges the whole day and on the 22nd a bit in the morning and then it stopped. And if I should have ovulated on the 21st/22nd could I still get pregnant from the sex on the 20th? Sorry for the confusion, I just want to get an idea on how all this works. Thank you!
