Thank you Clysta for your reply. I actually have pills with me which i was supposed to use soon as i have my period however i wasnt really that confident using it since ive never used one before. My doctor briefed me with a 21days pill where what she has prescribed has 28tablets so was bit confused what to do. I didnt have time to consult her again as i was flying abroad as i worked overseas. So lastnight out of tension knowing that my husband was not 100% sure, i have taken the pills. Will it have some effect still? and shall i continue using it?
There's not really too much that you can do. If you want you could opt for Plan B pills, but they're expensive. (Around $50, and they have an 85% success rate)
In terms of if you can get pregnant, yes. Withdrawing isn't protection and if that's your only form of birth control it's a very poor one. You need to use condoms and birth control at all times. There are a few risks getting pregnant so soon, the main ones being hemorrhaging, ruptured uterus, low birth weight, or premature delivery.
You should remember that since your body is still recovering from the birth and surgery, your cycles aren't going to be regular. You won't be able to use online ovulation calculators and such. Wait 2-4 weeks and take a pregnancy test with first morning urine.
