Sick of MIL

I've had quite a complicated pregnancy right from before we even conceived. Multiple reoccurring losses, needing medial assistance for over a year just to try and stay pregnant, being high risk and on medication from the day I ovulated. Have needed scans every 2 weeks from 6 weeks and I'm not 34 for it's been a lot... I've had nearly all of the not so nice pregnancy symptoms leaving me bed ridden for majority of pregnancy, it's sucked but we are forever grateful to be at this point. MIL has basically been on my back about how I just need to get on with it. The last few weeks my pelvic girdle pain has been agonising and I really can't leave the house without causing myself more pain and she's giving me grief about it, an urgent referral has been put in for physio for me and she's told me I shouldn't be wasting services other people need. I got diagnosed with gestational diabetes and she told everyone I got diagnosed because of how lazy I've been during pregnancy. She told me I wasn't allowed to tell anyone the gender because she didn't want to know. (We weren't planning on telling anyone so we could share something special about the pregnancy without everyone else knowing anyway) She's told me if it's a boy the middle name has to be ... and if it's a girl it has to be ... . Lots of things which have been bugging me but trying to not let bother me. About 2 months after we told them we were pregnant they booked a 6 month long trip to New Zealand a week after our due date which annoyed both me and my partner, but then my SIL got pregnant, due 3 months after us and they cancelled the 6 month long trip and rebooked a 8 week long trip leaving a week after our due date and back 3 weeks before hers so they can help her as much as possible. Baby has been measuring big this whole pregnancy but in the last 3 weeks baby hasn't grown at all, we are being seen twice weekly in the fetal assessment until to keep an extremely close eye that baby is okay and they can't figure out why baby hasn't grown. We are also having weekly consultant appointments to keep an eye on things, so 3 appointments a week. Went from 97th percentile to 30th so it's quite concerning and we have a lot of anxiety surrounding this. Basically MIL has told me to stop over reacting, she said they would have told me if they were worried but clearly having 3 appointments a week to monitor baby is saying they are worried considering healthy pregnancy's get two scans. She keeps saying oh baby's a healthy weight still so there's no need to worry but she's not getting the fact yeah baby might be a healthy weight but they haven't grown at all. They've lost weight which isn't healthy. It's really pissed me off, we are preparing for a possible early birth, before 37 weeks and she dosent seem to grasp the severity of what might happen. Bumped into a family friend and she said oh MIL has said your pregnancy is flying in, she said it's been an absolute breeze for you, I heard SIL is really struggling, your MIL said she's been down cleaning her house and stuff to help her out. Meanwhile SIL pregnancy has been fab compared to mine, she had morning sickness until about 16 weeks, quite severe but didn't need medication or anything, she could keep meals down ect. Meanwhile I had to go on IV fluids 4 times, on medication and only stopped getting sick at 29 weeks. Sick of feeling so shit with how MIL is treating me, and how she is portraying me to other people. Hateful that it's just me she's giving the hard cold shoulder too about being unwell in pregnancy meanwhile being so sympathetic towards SIL. She keeps going on about how special SIL baby is because she was trying to get pregnant for a year and they thought it wasn't going to happen- she's 2 kids already and she's 39 so it's not a surprise it took a year. But yet she won't recognise how special our baby is and everything we've gone through to get to this point. Sorry for long post, and if I'm rambling or it's not fluid. I just needed to rant. It's really getting to me and the closer we are to baby arriving the more anger I have towards her.
