Unsure!

So my last period was the 8th of may.

Lasted 2 days.

I’m currently on the pill and the last time I had sex before my period was the 18th of April, unprotected. But had a period since. I’m now on the pill and not due my period for a little bit yet, but I’ve been having the most vivid dreams, like extremely vivid. My breasts are very sore to touch, now this alone I would say is just period coming, I’m tired allll the time like fall sleep at the drop of a hat and wake up like I have only had an hour!

With my last 2 pregnancies my dreams always went vivid. Like movie I can recall all day.

I’m just unsure as to it all and was hoping anyone had any ideas? I’ve gained a little weight as was wondering if maybe that was the cause, I’m going to do a test but I just simply don’t think that’s the cause as I had a period😬!

All help appreciated

Sorry for the essay.
