Hi everyone, I have a question ? My last period was on February 19. I had sex with my husband on February 26–27 — does that mean conception was in late February or in March???? My cycle is 27–28 days, can someone calculate it if they know? ? One girl calculated for me and said that if conception was in late February it would be a girl, and if in March it would be a boy. Now I'm wondering who it will be, although the most important thing is a healthy baby ?
