Perhaps Manitoba offers free midwifery care to women as is the case in Ontario. Here's a link you might want to check out, it has a phone number you can call to find out if that's the case.

My wife and I are also expecting a child and like you she does not qualify for our provincial healthcare yet (OHIP), so we've engaged the services of a midwife. We do not pay for visits/consultations with her (right now once per month, but further along in the pregnancy it'll be down to once per week, just as it would be if we were seeing a physician), nor will we have to pay to have her attend the birth along with an "assistant" midwife. Midwives are at least as qualified, legally and practically, as a physician when it pertains to pregnancy and childbirth. Their services are covered by the Ontario government whether or not the client/patient is a bonafide resident of Ontario. What we do have to pay for out of pocket is bloodwork and ultrasounds (less than $500 total) and if the birth must occur in a hospital (we're planning a home birth if at all possible), we will have to pay hospital/attending physician fees which, I'm told run around $3000 for a "normal" birth and $5000 for a c-section. As long as there are no complications, the midwife is legally permitted to attend the birth at home and does not have to refer her client/patient to the hospital. We've found the entire experience with our midwife to be excellent to date. My wife is 23 weeks pregnant, due date is Christmas Day!
And remember, once the baby is born in Canada, he or she is automatically a citizen and immediately qualifies or medical care should there be a need.
Please don't let uncertainty and stress cause you to abort your baby, things'll be fine. Just put a push on and get your paperwork submitted as soon as possible.
All the best!
