Hi all!

So my husband and I have decided to try for another baby. So I stopped taking the pill about 3 weeks ago, had a 4 day period and then (last 6 days) started taking opk to try and figure out when I’m ovulating I’m also taking my temp and keeping an eye on my mucus and in the past 2 days experiencing very very mild cramping (I’m assuming I’m beginning to ovulate) but my tests are neg and I actually think the neg line is nearly non existent compared to the first but they are both extremely light so I can’t really tell. Do you think I may have actually ovulated just after my period or is it more likely still to come. I’m day 13 of my cycle now. Just needing some advice
