All totally normal feelings and reactions.
I've had 2 mc.
First pregnancy, unplanned, 18, on low wage living in a bedsit, on the pill correctly, had just split a few weeks earlier from father, totally threw me. Complete mc no need for surgery or treatment and told very few people. Kept it to myself for years. Felt guilty (because I hadn't been sure if I'd have continued the pregnancy in the circumstances), didn't feel I could tell the father as we weren't speaking, seemed pointless causing him grief too.
2nd pregnancy, married, planned, very happy. Felt very unwell and passed out at work, sent home, put it down yo hormones plus I'm prone to low bp/fainting anyway. Next morning spotting and just felt "wrong" really hard to explain and then husband took me in to get checked over. Long story short, was twins, 1 ectopic, 3 surgeries as a result and endo discovered and treated.
Emotionally it was like all the "stuff" from the 1st mc got wrapped up with the 2nd and I really struggled, swinging between being desperate to ttc again (but wasn't allowed as needed to heal from surgery plus was on medical treatment for endo that was contraindicated for pregnancy) and thinking/feeling maybe best to not even try, not risk more heartache, illness, surgery etc.
Feeling guilty (raised Catholic so some thoughts of it being a punishment for pre marital sex, considering abortion with 1st mc), feeling a failure as a woman and a wife, feeling I was unreasonable for feeling so upset considering both were relatively early (pre 10 weeks), feeling angry, scared, pissed off, scared to have sex but also desperate for intimate connection to then husband, being angry with husband for getting me pregnant, for not seeming upset or seeming too upset, then feeling guilty for giving him a hard time and trying to support him too.
Then when pregnant with dd feeling anxious, not wanting to tell people for ages, being so cautious with what I ate, drank, breathed! Again feeling a failure as a woman and a wife when medically the pregnancy didn't go great (fainting, spd, GD, spotting throughout, latter stages pre-eclampsia) then the birth went pear shaped too!
But dd is now 18, big lump of grumpy/funny/intelligent/loving and I'm so glad she's here.
I couldn't have any more, but I'm so glad she's here.
Mc brings so many emotions, so many thoughts and fears.
None of them are wrong, they just are.
You're grieving, you're scared, you fear what the future holds that's all normal.
It's a process.
You don't "get over it" you do get stronger and better at coping with it.
Be kind to yourself and your partner and try resources like the mc association if you think you'll find them helpful. Talk here and look after yourself.
