Me and my SO had BD on 5/12 3 times that day, then on 5/13 we BD'd once. On 5/13 I had spotted from then till 5/15. Yesterday we then had sex again, and I was on CD 14 DPO 3. Today it's CD 15 DPO 4. My period according to glow is due in 10 days. Before having sex yesterday, I tested and all of them said negative. When's the best time to test besides my late period? Please send baby dust and prayers. We really would like a little one.(:
