No Idea What to Think

So I have a birth control implant in me (have for 5 months) and it's thrown my cycle out of wack. Here's how it is: I get my period for 5 days then I'm off for 7 then back on and so on, so it's a really short cycle. Well I know birth control isn't completely effective. I am very sexually active and my guy doesn't pull out when he cums. I had just gotten off my period and we had sex, and again for the next 3 days after that which i know is most likely my most fertile days given my cycle being so short. I'm currently feeling super nauseous, going pee A LOT more than usual, very bloated feeling, have slept almost all day for 3 days straight, and moody. Can someone please tell me what's up lol I just need to hear some input before I lose it haha.
