Symptoms in each pregnancy and cycle length

J

so I have a question for you ladies. I was just wondering if different pregnancies can trigger different symptoms each time for the same person. I had a chemical pregnancy recently and that month I noticed a lot of soreness in my nipples. This month I am late again (currently 7 days late according to Flo and 5 days late according to glow.)

and I feel no symptoms of my period coming but no breast tenderness either. This makes me feel like I'm out this month, but I try and remember I'm not out till AF shows. Since I felt breast tenderness in my first pregnancy should I expect it when I get pregnant again? Also, I noticed that in the last couple months my cycles have gotten significantly longer. Last year they ranged from 26-28 days and now for the last 3 months they have gone up to 37 days. I haven't really done anything different and I haven't been any more stressed than I usually am lately, I was just wondering if this seems normal. Thank you for your help ❤️
