Pregnancy symptoms ?

I'm having these symptoms and I'm scared they're pregnancy symptoms as I'm super late for my period and the only protection I rely on is my implant ( but my implant is super bent I can feel it ) 
But these are my symptoms
-sickness at morning and night 
-bloating 
-leg cramps 
- a lot of weird discharge 
- no period for 4+ weeks ( which isn't normal as I usually have periods every 3 weeks on the implant it's like clockwork and always has been)
- and I'm having super weird cramps at the side of my stomach 
- I'm passing urging and pooping a lot more than usual 
I'm so worried that I could be and taking a pregnancy test is the last thing I want to do as I'm only 18 and so is my boyfriend. Any help would be appreciated.
