Op please take a deep breath and put your DP firmly aside .
Time to really think about your future and take control of it.
Now just be you, ....you are 32 you must have considered whether you want children? What are YOUR feelings, have you ever seen your future with children, or been firmly against the idea?
What do you want your life to be like at 40, 50 and 60, child free, with a family, or what....?
At 32 you do have some time but not too much if you want children, l started trying at 34 and it took me until 38 to sucessfully have a baby,
fertility does drop off after 35.
I cannot stress enough (from experience) please forget everyone else for now including DP and think carefully about the life you want..
Once you know if you want this baby, you can talk to DP, be firm and strong, anyone who has sex runs the risk EQUALLY of accidentally falling pregnant, it is not just a womans fault or responsibility, but it will be your body and your decision, so make sure you make the right decision for yourself first.
Good luck
