How far along are you?
Ill share my story with you, take it or leave it sweet, after ultimately is it your decision....
I became pregnant 2 years ago, so that wouldve made me 21years old...not planned, only found out when i wanted to eat pickles out of the jar in every shop i went into

....anyway, long story short...i had a scan, i was 6 weeks - if i had been over 10 weeks, i wouldve kept the baby... my own decision was that i was going to have a termination, based on (and solely on this reason) that i was under 10 weeks... I didnt take anything else into consideration except for what was going on right there and then.
Ive regretted it ever since.
My mother is a midwife, she supported me fully, (as did my partner), i had a medical termination as the thought of being knocked out scares the monkeys out of me. As soon as i sat on the toilet, having contractions (that lasted a beautiful 5 hours), i only
then began to think about what decision to make....
The last 2 years, i havent stopped thinking, "oh, today 'it' wouldve been a year old" - "i wonder what id be doing now if id kept 'it' "
Im not trying to sway you, it does sound like i am though, im just pressing you to really, really think about....i know you are, but you need to think about it in a way that only involves you and your child. Sounds selfish, i know, but you might leave your man, he might leave you....the futures not set in stone...
As for not being in that stable environment....what if you never are? There is never, ever a
right time to bring a child into the world, otherwise its too mechanical. Every mother is succesful, no matter what their circumstances are.
I wish you the best of luck in your decision.... be logical, dont let too many emotions get in the way...but then dont do a me and be nothing but logical and cold in your decision making....
