AITAH for pointing out my GF's bad hygiene?

I (m28) have been with my gf (f27) for seven months now and went full exclusive three months ago.

She's everything, smart, kind, caring and drop dead gorgeous to me.

However, she has worse hygiene than a neanderthal. She lives a studio apts so it small. Since started dating her I've avoided spend time there because it's always dirty. But I never said anything because it's her place.

She does not shower often and has strong BO. Like bad enough that I won't have sex with her unless she's recently showered.

Here's where it gets bad.

She's on her period and three days ago she was having a really rough day, so called her and asked her to come stay at my place until she feels better that I can't cook and take care of her and allow her to rest. She was take the week off from work because it's was so bad.

She came to my place and didn't bring any feminine hygiene products. I have to run to the store at 3 am to get her stuff because she'd been wearing the same pad for so long that it leaked on my bed. I didn't say anything as she's stressed.

The next day I came home from work, and she the pad from the previous night on the bathroom floor without even wrapped it.

I was pissed and called her out and said hey that's gross I don't wanna look at that while I go use the bathroom.

She got really mad and said I called her gross.

I clarified that having a period is not gross and is a natural thing but leaving a bloody pad on the floor of someones home is nasty.

She lost it and said made her feel gross and bad.

Was I an asshole here for calling her out?
