My periods have always been irregular and all over the place but since I had a baby 9 months ago it has been less erratic, cycle lengths anywhere between 37-45 days. Have been using condoms but on cycle day 33 had an accident and condom broke. I am fairly sure I already ovulated before that, didn't do ovulation tests but had some cramping as I have had before when I ovulate. Is there a chance of pregnancy or am I just being silly?
