Long cycle

I’m 43, 138 lbs. I’m a fitness trainer and bodybuilder. I’ve always had irregular periods since I was young. I have been on birth control for many years and then went off of it for 10 years. In the last six years I have had two Nexplanon’s and currently still have one.

In the last six months my period has been all over the place. It’s not a normal 28 or 32 day cycle. It goes longer than that. My body is super sensitive to medication, nutrition changes, stress etc. because of my fitness, most women don’t even get a period, but I always have, even though the doctor told me I probably wouldn’t get it using the Nexplanon. 

It seems like my PMS is more intense including bloating and most recently tender breasts. I can even tell when I’m very irritable 😡 I understand as I get older things will change but I’m not even near any kind of pre-menopause, as my mother didn’t enter that until her mid-50s. 

I am constantly worrying that I’m pregnant even though I have the Nexplanon 🙄. Because my cycle drags on I take pregnancy tests just to stop worrying. It’s literally obnoxious.

Does anybody else have anything like this? I’m going to attribute it to the following:

My age

Nutrition changes

Stress

Nexplanon
