Late period/ should I worry?

Ruby

So I'm usually always on time when it comes to my period. I've had some late as well or even twice where I skipped a month. I had gone to the doctor and they told me that maybe it was stress or my hormones. I was predicted to get my period on the 25th of August. Usually get really gassy and heavy cramps before getting my period. Up to today, no cramps or gas. My husband and I have intercourse with condoms. Well, we start without and when he feels it, he puts one on. I weighed myself today and I gained about 7 pounds 😩 I don't know what to think. I need help! Would it still be early to tell or am I over exaggerating?
