HELP! Pregnancy bleeding or AF?

My boyfriend and I have been TTC for about 3 months now. My period is very regular, heavy and typically lasts about 5-6 days. This month I got my period 4 days early which was weird because I didn’t have any of my PMS symptoms(cramps are usually a big issue for me). The first day of my “period” was only light pink creamy CM with a few spots of blood. The 2nd & 3rd day was like my normal period, I even got some mild period like cramping. On the 4th & 5th day my AF completely stopped and there was only pink/ light red spotting when I wiped. Which was odd to me because my “period” was so short. I thought my period was over as today is day 6 and the bleeding has picked back up like a light period but a pad is still needed. During this entire time I have been experiencing mild headaches, on/off aches in my breast, lots of back & hip pains, hot flashes & a pain that is somewhat indescribable in my pelvic area (not so much pain but twinges in both sides). My boyfriend thinks I should test but I’m scared and unsure😩 I feel like I could be pregnant but the on/off bleeding has me thinking that this could just be a weird visit from AF😔
