Just because this happened during your other periods doesn't rule it out as a symptom of you being pregnant. Thats not a smart way to think. That would be like me saying i get sick and throw up every time I get my period, so that's not a sign of morning sickness for me. That's just a sign my period is coming. Did you get your period though? And even if you did bleed was it like a normal period or was it super light? Cause it could have been implantation bleeding.
I know I'm not pregnant because I have gotten my period twice while this has been happening and it hasn't gone away as it normally does which is why I am wondering why this is happening. I should be getting my period again soon but the symptoms have stayed the same the whole time.
Why do you say it's not PMS? If your period is due in the next few days, and you're not pregnant, it seems like it probably is exactly PMS.
On the other hand, if you're thin, and you run 5 miles a day, and you also do an intense exercise video every day, I would be very surprised if you're ovulating at all. That's too much physical activity - usually women engaging in that have cessation of periods.
Have you taken a blood test and a HPT to be 100% sure that you're not pregnant? Cause it could be a possible sign. When I got pregnant that exact same thing happened to me but I dismissed it as a symptom of pregnancy because that always happens to be before my period. I took me 5 months to find out I was pregnant (I'm very irregular and I dismissed my three days of morning sickness as heat exhaustion because I spent the day of and the day after at hurricane harbor) and even then I only took the test to prove my friends wrong. I didn't gain any weight till I was 30-33 weeks.
It used to happen to me a lot as well. I think it's just hormone fluctuations especially since your kinda stressed right now. I would just test again in a week or two just to double check.
That used to happen to me alot for a while. I'm not sure what causes it, but eventually it stopped happening
