Help !!

My boyfriend and I have been ttc for about 6 months with no luck whatsoever. I was hoping this month would be different, but instead my period came 4 days early! If anything, it usually comes late, so this is the first time this has happened. On the first day I usually have a light flo, but it was very heavy and my cramps were EXCRUCIATINGLY painful. I almost had to have my bf take me to the hosptial, I usually get bad cramps but never that bad. I couldn't stand or move for 3 hours straight, and the rest of the day it was hard to move or walk. Day 2, yesterday, was decent with medium flo and very little cramps. Today it is day 3 and basically like I am spotting. Also, for the past 5 days or so I have woken up with this weird dull achy feeling in my lower stomach, not necessarily cramps but like that dull feeling you get when you are anxious.

What is going on rn? Should I go to a doctor or something?
