Is it normal for my opk’s to get darker after ovulation? It’s been dark for 7 days now and looks like it’s getting darker...even during my early evening testing...I’m very sure I ovulated around last weekend/beginning of this week...I didn’t have Aunt Flo this month, just spotted for 3 days. I was on the xulane patch but took it off when it expired and I started spotting (that’s usually when Aunt Flo starts). I haven’t replaced but decided to ride the ttc train early (wasn’t going to start until the end of the year). What do you think? The blue Line graph is my temperatures. The plus signs are positive opk’s. X and PM is when I did the do.
