hi guys! Need some advice… my cycles 23 days long, my flo app says I should ovulate on day 10. I done the ovulation tests from the day my period ended all negative, then today ( day 12) the line has started to go darker, not as dark as the controll line yet but I know it’s will over the next couple days! So my question is do I have sex now? Before it starts to get darker or do I wait untill I get a defined dark dark line? Confused! Thankyou
