What do you think, am i pregnant?

I came off birth control for about a month because i thought i was pregnant. My period came on April 22nd and i started my pills back up on April 29th (at night). I did not realize that you had to be on your pills for a certain amount of time before they came effective and my boyfriend and i had sex twice on the 1st of May. He did come inside of me both times but i didn’t think anything of it. On the 9th of May i had some cramps, which wasn’t normal for me. I read that this might be implantation cramps? Since then i have had MANY symptoms including sensitivity to light, gas, back aches, headaches, pressure in my lower abdomen, frequent (i guess you could call them nose bleeds), and peeing more frequently. Yesterday morning i used the restroom and as i was walking to my class i felt as if i wet myself. I later checked and it seemed to be a watery, redish discharge. I’ve never had that before and last night i woke up multiple times to pee and i felt as if i was going to vomit. I’m really worried that maybe i had a miscarriage? i took a pregnancy test yesterday (5/17) and it came back negative. Please help! Thank you so much! Sorry i know that is long…
