Hi, i'm new here and need some advices from everyone here.
I'm a mother of two son and still try to conceive to have another child. I bought this mini microscope and just not quiet understand how it really work. Well, I just stop my cycle about two days ago. I used the mini microscope ( saliva tester ) last night and it show some ferns. Today, I try again, it show ferns more. Am I ovulate? If so, why it's so soon? Should it be around the 13 days by counting my first day of menstrual cycle day. So, actually i'm just 7 days ( start on 21-end it on 26 ) on 27, i'm already ovulate? Is anyone here using the mini microscope saliva tester? I'm dying to conceive. Trying to have a baby girl cuz I have two son already. Also, what sex position is better for the man sperm swim up faster to reach the egg? Any advices will help.

Thank you
