I'm so torn

NAT

I hope this is the right group to message but I'm in the worst situation in my life and would love to speak or hear stories. Please bare with me as I tell you some info... I'm married and have 3 young beautiful children ( 7.5yrs, 3yrs and 1.5years)...all high risk as I'm over weight. My last pregnancy was the easiest but I had pregnancy diabetes. Yesterday I found out I'm pregnant. I thought we where safe as we have been having sex out of my green zone on glow but my body had other ideas and for the first time i seemed to have ovulated early. I plan on meeting with my doctor this week to discuss what I feel is right..all my kids have been c-sections. Our financial situation is crap but not forever. My hubby works away often so I'm left to bring them all up on my own. My middle child also has autism. I'm scared and just looking for advice... that's all. Thanks for reading. Please also know I've been crying all day and if you could be kind xx
