Different symptoms second pregnancy?

I knew I was pregnant a month ago because my breasts are ALWAYS tender/sore a week exactly before my period and a couple days before my period they still weren’t sore yet. So I took a few tests, all positives. Sadly it ended in a chemical. Well, af is due in 4 days, and my breasts hurt as they always do before af. Has anyone else experienced this and still ended up pregnant? No sore breasts first pregnancy then sore breasts the second?
