Weird smell before period????

I’m on cycle day 33 and my period will start in the next few days, my cycle is usually 33-35 days, I’ve had tender nipples and PMS. For the past two days or so I’ve noticed a much stronger smell coming from down there, it’s not absolutely disgusting just stronger than normal even after taking a shower this morning. I have a little creamy discharge, I had sex with my boyfriend December 9th so idk if that would affect the ph at all. Any ideas? Has anyone else experienced a stronger smell before period?
