I need to vent!!!😤

Today I went to a family party with my boyfriend and we were eating having a great time. 5 minute into us eating his mom brings up one of his aunts and says ( so and so have been married for 6 years and have not managed to get pregnant. she is trying so hard and doesn’t let her body relax. She laughs and says I clearly don’t have that problem ) at this point I was really upset crying hurt frustrated and really didn’t want to be there! I lost my appetite and just walked out! My mother in law clearly knows we are trying and how I was on my period today so I’m extra sensitive. I feel like she was trying to out me and honestly I’m fed up with her shit
