When I was 13 I had surgery as I had a cyst on my ovary & Fallopian tube I had to get these taken out so I now only have 1 ovary&tube.. I've never thought I'd have to worry about being pregnant but I am as I had unprotected sex with my partner for the first time since we have been together (2years) I'm due my periods on the 10th-16th I only had unprotected sex a week ago & I'm experiencing pain not in agony but really unusual annoying feeling... And constantly tired.. I'm scared to visit the doctor as it might be another cyst and I don't want to endure the pain I had when I was 13 or could I be experiencing early pregnancy signs what to do please help I'm 20 now and never wanted kids but now facing the fact it might be another cyst is making me scared as I won't have an option for kids when I'm ready thanks
