Can stress delay ovulation? (Recently had quite the scare when I developed lump and an infection in my left breast even though I haven't nursed in 3 years. Everything turned out fine but it was very stressful and scaring.)

How about having a 12 year old daughter who has, in the last 8 months, began being visited by AF, I feel like everything is working against me and throwing me off this month.

My cycles have been pretty consistent until this last month when I finally got my husband home, (he works in the oildfields, for months at a time, over 900 miles away). He is only home for two weeks (just left Saturday) and we planned it for him to be here during my fertile window. Have been documenting and keeping track for the last 5 months. This was our 2nd attempt at TTC baby #3. Now it's looking like my ovulation was off by almost a week! It was supposed to be on Wednesday or Thursday of last week but my OPKs never came up positive. I thought I had a bad batch. But I've continued to test to be sure and it looks like I'm having my surge today. 😢 Could be tomorrow, it's hard to tell if it's as dark as or a tiny bit lighter than the control line. Last time we did the BD was Saturday morning. It's now Monday. I'm so worried that we didn't conceive and will have to wait 2 or 3 more months to try again. Thoughts? Still think we stand a chance this cycle? I'm feeling really down because it seems like we will never be able to line up my window with his days off. 😭 Especially if stress is throwing it off since it's always a little stressful when he first comes home. We all have to readjust since he's been gone so long. Don't really know why I'm posting this other than I'm tired of taking my friends and family's ears off about something they can't really understand. I'm lost and thinking about this from the time I open my eyes to the time they close. I'm beyond baby hungry and it's making me crazy!
