Help!!! Trying to figure this out :(

So me and husband are trying for our first baby. We have been trying for 3 and half. My period are really irrgular. So I had my last period on August 11th - 21st. And then last week was my ovulation week. We had sex every other day pretty much. I started spotting last night & it was bright pink and very light. I didn't need to use a tampon. The only time I would see the spotting is when I whip after I'm done with the bathroom. Today my spotting gotten a lil heavier. Im really worried because it has been a week since my last period. I don't really understand what is going on with my body. This is all so confusing. I want to believe it might be implantation bleeding because that happen 7-12 days after ovulation and that also make sense. I need second opinion from you ladies ❤️ My husband want me to go see a dr but I feel like they aren't going to do much to help me.
