Is this normal ??

hey everyone. So recently for control for the first time and I just finished up my first pack last week. Today I’m supposed to be starting a new path, but I’ve been having some issues. I started my period on 10/7 and ended it on 10/9. Usually I have. The last for five days, but I know that starting a new birth-control can change the cycle of your period and stuff like that. I’ve also been experiencing some weird symptoms on it like nausea, hunger, weight gain, fatigue, back pain, stomach pain/period like cramps and mood swings. I experience all of this like everyday . Although, the other day me and my boyfriend tried to have sex for the very first time. It was both of our first times so we were kind of nervous I’m not really sure if we were doing stuff right. He was putting his condom on he started to jack himself off a little bit to make himself harder. This kind of freak me up because I don’t know if he touched precum or not while doing that. After he did that he put the condom on or at least tried to but it didn’t work. I then made him open up a new package to try again but this time I didn’t let him touch himself before instead I tried to get him hard myself. He got the condom on and he tried sticking it in but it wasn’t working so we decided not to go through with it. Let me just say when he tried sticking it in he barely got the tip in there before I told him I was too nervous. Even though we didn’t really go through with it, I began to get really nervous. I have really bad anxiety about stuff like this because I’ve gone through a lot so I tend to freak myself out alotttt over things like this. anyways after all of that I started experience some cramps and some back pain and this just freaked me out even more. I woke up the next morning too with some cramps that kinda felt like it was period cramps and some discharge that had some coloring in it. Later that day after the incident I went to a pumpkin patch with my family and it was pretty hot outside so I kind of feel like I got sick from being outside for that long. I don’t know Im totally freaking myself out and I’m starting to feel extremely guilty and just awful. I really just need someone to calm my nerves down and I help explain if this is normal or not. Please let me know anything will help. Also please be nice in the comments I know this all sounds crazy but I just really need to know.
