Denying my baby 😢

I'm currently 11 weeks 1 day pregnant... this is my second pregnancy this year (first one ended in a MMC in May 2017). My boyfriend & I have been together for well over a year. Getting pregnant was never actually planned but it was something we weren't preventing. Well when my BF told his mother who lives out of town & who I've never meet, she replied with "I told you not to let that girl trap you" and proceeded to try to convince my BF that I could be faking the pregnancy & that I went as far as faking my ultra sound photos.... when I asked my BF if he felt that way he said no, just his mother. But I'm so upset that he didn't even really stick up for me, he brushed her & her comments off & doesn't even think anything of it. When I saw messages of her saying "I won't be sending any gifts unless there is a DNA test" my heart literally shattered. I've never cheated on my BF. He's actually the one who's cheated on me a few times.... but I've never ever done anything with any other guy since before I met my BF. I'm so hurt by what his mother said & I'm kinda hurt he didn't say anything to correct her or "check" her & her hurtful words. Now apart of me doesn't want to even talk to him about the baby & I definitely don't want her to be apart of my baby's life with that attitude. I've been by her sons side through all the good, bad, ugly & flat out hurtful times while she doesn't even call to check on him. They don't have the best relationship but that's still his mother.... what do I do? 😢😢😢
