Help!! I don’t know what to do!

So as of August, my fiancé and I have been TTC. For about a year now, I usually spot around my ovulation time. Nothing to be alarming. Lasts maybe half a day. And that’s pushing it. Well the first month we were trying, there was just a little more blood than usual. It threw me off a little bit. I thought it was implantation bleeding, but it wasn’t. September and october were normal. So on Wednesday, the app said I was ovulating, which I figured it was right because I was having “cramps” on my right side. I went to the bathroom after I got off work and there was blood. So I was like “yeah. I’m ovulating. Let’s get to BD!” As we were doing it, it felt like my cervix was low and he was hitting it every single time. I pushed through it because we really want a baby 🤷🏻‍♀️. So yesterday after work, I went to the bathroom at home and there was blood again. It was about what is normally there during ovulation. So I was reading things online and scared myself into thinking I can never have kids. So I stopped and just hoped it would be gone today. So this morning I woke up, went to the bathroom. And blood again. Like I’m so confused. I don’t know what it could be. My cycles have always been regular. I’ve been taking prenatals since about the beginning of October. Is this all normal? Is this a sign I can’t have kids?
