late period.. have always 100% have had safe sex

Hey! I need some assistance. I have had protected sex 100% of the time, condom and a non hormonal birth control pill I take every day at the same hour because I was breastfeeding, and I have no issues now even though I do not breastfeed. I have gotten my period since my daughter was 3 months old and now she's 6 months so 3 months. I'm on a 35 day cycle, and usually not late more than 2 days. I've had PMS symptoms about a week ago and that usually is moodiness and irritability and I know my period is coming soon haha. I'm now 3 days late. I'm very scared to take that pregnancy test. I have been so safe, and I cannot afford another child.. I don't personally have the heart to have an abortion.. Seeing what my daughter became from those little group of cells.. There's no way.
