Help!!

Ashley • 21. TTC for 7 months now. My boyfriend is the best thing to ever happen to me. We just want to start our family already!
I have a question! On June 12th I had my period, it ended June 17th and my boyfriend and I BD'd the 18th. On the 23rd, I had light pink bleeding and I had asked someone if it could have been implantation bleeding, but they said it could have been ovulation spotting. Okay, that's fine. So then 2 weeks before my expected period, on July 11th, I started bleeding. And since then, I've been having more and more pregnancy symptoms, but I took that bleeding as just a period. Since my d&c in January, my cycles have been 42 days apart, but that cycle would have been 28 days if that was indeed my period. I have been nauseous, sore bbs, frequent urination, always hungry, bloated, gassy, heartburn, headaches, dizziness. I'm just wondering if you all think I should take a pregnancy test or not? Because if that was not my period, af was supposed to show on the 25th!
