I am sure you are a great mother to that seven month old. It probably will be tough, but since you are a mother your motherly instincts will kick in. It will be hard financially, but if you know deep down you will be able to handle it then by all means everything will be okay. If you truly do not know, there is always adoption. I know that is hard, but you want the best for that baby. Goodluck hun.
If you already have one but don't think you can handle another you need to be on birth control to prevent this
I pray you do NOT m.c., I know it is very hard & scary to endure something of that nature. If you do manage to have a sticky bean & feel unable to properly care for baby #2. I advise you to look into adoption, if you feel thats a more fitting answer. Then you should look into some kind b.c., to prevent any other worries for you hun . But I hope everting works out perfect for you hun!
Who told u that u might miscarry and what was their reason for telling u this?
