I think I’m going crazy

So I had an EP in Nov 2018. I got my first period 6 weeks after my surgery (got my left tube removed, due to rupture) with my first & second period post op with absolutely no pain or symptoms. I am now on my third period and it’s extremely painful and I feel this tugging pain on my right side. I feel like what if it’s happening again, what if I go through this traumatic experience again! Mind you me and my husband have started protecting since my EP as I feel like I’m emotionally too damage to try conceiving. I know we’re protecting and have a very very low chance but my mind is playing games and I’m loosing my shit over this. Has anyone gone through this pain with their period after their EP?
