Health and Anxiety... need some advice

Hey guys, so here it goes.

All my life I’ve struggled with my hormones. I’ve never had a regular period and I’ve always spotted randomly. Let me just add that I’m 23 years old and I’ve never weighed over 110 lbs.

I went to the OB when I was 18 for my first exam to try and get some answers as to what was going on with my periods. She did a pelvic exam along with bloodwork and found no issues or abnormalities. Told me to put on some weight and see what happened.

Obviously putting on weight is hard but I don’t feel I’m extremely sickly looking, I’m healthy. Period still only comes once every 3-4 months with spotting occasionally in between. I don’t want to be put on birth control and this I stand firmly by. It’s just a decision I’ve made.

I’m scared to death. 1) because I’m afraid I won’t be able to ever have kids and 2) I’m afraid to go back to the doctor and be told I have something seriously wrong even though last time I was told I was normal. I know it’s just how my body is but I want some other girls going through the same thing to just tell me I’m not crazy and that there is hope for people like me.

Thanks guys. ❤️
