Confused :(

Hello

So I’m 23 yrs old my bf and I been trying to conceive for almost a year. My period is very irregular so I started taking some prenatal supplements and they’re suppose to help you regulate your period as well. I been taking them for almost 2 months already and I been having this for about 1 was. Sore boobs, cramps, lower back, headaches, and Hester and today I had this bleeding and I want to think is my period but my period is not due yet. Could this be implantation bleeding? Yesterday it was pink with a little bright red blood.
