BAAD Cramps? Should I be worried 😟

So I’m 7 weeks 5days per this app but have first ultrasound to get actual DD on the 01/29/20’! Anyways I did get pregnant within a month & a half of coming off Nexplanon I have heard stories that you need to let your body rest a bit to get all the hormones out & people miscarried etc . I haven’t had a period since coming off of it so I took a test a month & a half later & it was a BFP! So this is my 4th pregnancy & I’m still new to a lot of things but I am having some REALLY REALLY REALLY BAD cramping in my lower abdomen most likely where my little blueberry is & up my stomach to the middle feels like I’m finna start my period mixed with bloat etc . I can hardly move or eat , but I have been making sure I’m not spotting or no clots or blood ! Nothing so far , but this pain is unbearable . What should I do or is this normal ?
