Help please !! Any opinions appreciated!!

Am

We had a miscarriage in November. My cycles were always very regular and since then they still seem to be but they start a bit later now.

The issue is my boyfriend works a 2 week in 2 week out job. He used to be home perfectly during my fertile week and when I ovulated but now My period comes a bit later and he leaves during the middle of my fertile week. This is our first month that we got the go ahead to start trying again and I’m just worried it won’t happen because he won’t be home what do you guys think ? Is there still a chance ? Mhm fertile week is from the 17-23. I circled the day he leaves (Feb.20th) . Trying not to stress just praying my period comes early today or tomorrow would help ah.
