Period sex..

So.. my husband and I just got married 4 months ago... and the whole time we were dating he said he didn’t mind period sex as long as it wasn’t the first day or two of it which I agreed on because those were the worst days.. but now... 4 months after being married he told me he hates period sex and that it’s disgusting and that he only told me he didn’t mind it so that I wouldn’t get upset.. he told me that he wanted to wait until after we were married to tell me... should I be upset that he basically lied until we got married to tell me this? I told him that I wouldn’t have gotten mad because it is blood..and I do understand that even using a condom it could get a lil gross if you haven’t had to deal with blood for 7 days every month for 8 years.. should I be upset? Or just let it go? I mean... idk why but I feel a little upset that he didn’t feel like he could tell me... and waiting this long.. makes me feel like all of a sudden he thinks I’m gross or something.... (btw I’m hormonal because I’m currently on my period so I could be making a mountain out of a mole hill..) should I be upset?
