5 days late for my period 💔

I was 5 days late for my period this month and so gutted when I finally came on. Obviously I took a pregnancy test which was negative but only the one and I just hoped it was wrong. My partner works away around 3 weeks a month in total and next month was only our second chance this year where he was home and I would have been ovulating. Now that I’m late, it’s going to knock my ovulation dates back isn’t it? Which means he’s going to miss it. If so, that was our last chance for another 5/6 months 😭💔
