Am I pregnant!?

Okay, so this might be lengthy, please bare with me. So, my boyfriend and I have been trying to have a baby for a while, two years to be exact. And we have gone many more months disappointed, so we kind of gave up. Stopped stressing and just been enjoying each other. So, five days ago I realized that I should be starting my period soon. I was about two days late and wasn’t having any of my usual PMS symptoms. Such as sore boobs, cramping, upset stomach, and a major sweets craving. Had NONE of those symptoms. Then, I started noticing light pink spotting, so I assumed it was my period starting. But, it stayed light and pink, then turned into brown colored blood. Stayed spotting and brown and sometimes would be pinkish. Then on the 3rd day, my boyfriend and I had sex and it made me spot red for just a brief minute, then went back to being brown and light pink. Then it started getting less and less. It was also only noticeable when I wiped, wouldn’t leak onto a pad at all except for maybe two or three times but still wasn’t like my usual period. It’s been going away completely off and in the past two days. As for other symptoms, I have been very irritable and have no appetite, I feel super nauseous off and on, I have been having very intense dizzy spells out of no where sometimes, have been constipated for three days, and been very worn out feeling all the time. But, no sore boobs, no cramping whatsoever, and there is no flow to the bleeding. Don’t know what to think due to not wanting to feel stupid for wanting to test when I feel like I am just symptom checking.... please be nice with replies, I really need advice. Stories of you ladies’ experiences would be nice. Just want to know if I should just test or if I should just ignore it. I also don’t recall the date of my last period, I want to say it was around the beginning of July. Thanks for reading ☺️
