Adjusting to BC

Alright ladies, I need some insight here. I'm 19 years old, and I just started BC for the first time about 2 months ago, I just finished my first week of pills for the third month. Now what I've noticed so far is I usually will get spotting during the third week of pills and then my period will be super light during the placebo week, to the point where I don't really bleed, it's just the brown lining. Here's the thing though, I have pure OCD, something I'm not sure everyone's familiar with, and it causes me to have intrusive thoughts, currently manifesting over an irrational fear of becoming pregnant at a young age. So please just tell me I'm crazy and this is normal, BUT I've noticed that when taking the pill, I'll become extremely bloated, I'm emotional more so than usual, my breasts will be sore but not any bigger, and just other minor things. Thing is though, I've always taken the pill on time, and my boyfriend and I always use a condom just to double up protection, and he always pulls out beforehand even with the condom anyways. But my CM this past week has looked different than the past two months... I'm just still adjusting right?? It's all in my head.... right???? 😅😳
