Hello I'm new!

Robin • Author mother ttc 1 kid already engaged
I've been trying to conceive for 9 months on and off and now i think me and my fiance are getting serious about this. I think i haven't gotten pregnant because of stress and bad timing. My fiance is older than me he's 38 with one child and i have one and i feel his little swimmers do work, its just always bad timing. I brought ovulation strips but only two of them. I just wanted to test them out. I'm in my fertile week and due to ovulate on the 16th. Should i wait closer to the 16th to test?
