This is perfectly natural to feel like this. I fell pregnant by complete accident with third in December 2018. Had a 7 year old and a 4 year old and had been suffering badly with anxiety and depression and only just found some balance with medication.
We decided together to have a termination. We were never going to have a third. I was about to be made redundant in January 2019 and would have needed to find a new job pregnant. It all seemed hopeless.
The termination hung over me for a long time. I felt at times both numb and beside myself about our decision. Suddenly everyone We knew seemed to be falling pregnant as well.
Slow and steady we got through it all. My husband didn't seem upset by it one bit and wasn't greatest support but I didn't confide in him either as I knew he didn't understand my grief and guilt.
I both knew we had made the right decision but also it felt so wrong and I felt so badly for taking the opportunity for my two other children to be older siblings to a baby which I knew they'd excel at.
In January 2020 my husband lost his mother and then came the pandemic and we were both far from our families as neither of us are from England, where we live. We started to take stock of our little perfect family unit and all we had been through and decided that after all, what we needed was another little member of this family. I'm not sure if we would ever have come to that decision any other way. It seemed impossible to have a third in 2018 but then in 2020 it made perfect sense. 🤷♀️. I felt real shame and guilt trying again after that termination and so sorry for the baby we didn't have.
Anyway, long story short, we have now been blessed with our third baby. And it feels like everything is suddenly complete and how it should be.
Talk to your husband and get a feel of what is best choice. My only advice would be don't rush into anything to get it over with like I did, not even sure if that's on table for you anyway but if it is Allow yourself a bit of time to be absolutely sure. I think I was in shock and a bit numb anyway from anti depressants.
Know though that you can absolutely do this with a third without family help. My husband and I are like too big silly kids. If we can do it anyone can. It's also perfectly ok to feel worried and overwhelmed. Who wouldn't be?
