Could lack of PMS be an early pregnancy sign? 11dpo, Help!

A few days before my period I usually get really sore breasts and the day before/of my period I get cramps and backaches. The breast soreness starts going away as soon as my flow starts and the cramps and backache are strong until around day 2. I often take ibuprofen for it and use a heating pad.

Today I am 11dpo and my symptoms are much milder. My breasts have been slightly sore but not to the usually extent and they’re almost back to feeling completely normal. I got a slight backache yesterday and had one wipe where I saw just barely a hint of pink and nothing since. I woke up around midnight this morning and had more normal feeling cramps and a backache (still not the normal level) but they went away after like an hour and still no blood or pink. Usually once the cramping starts they ramp up and I spot soon after. Since then, I only have a hint of a backache.

My luteal phase is only about 10 days long so if I don’t start today I’d consider myself kind of late. I know this could possibly just be my luteal phase getting to a more normal length. All tests have been negative.

Anyone ever experience a stalling of PMS symptoms before a BFP?
