Had a “period” then found out about pregnancy?

Hi all, this is a post for some answers. Did you bleed heavy or have a normal “period” only to find out you were pregnant? Before anyone says that this is impossible, it’s not. My sister and mother both bled normal for the first couple months when they were pregnant and didn’t discover it until they were almost 3 months or so along. So my questions are these, how did you end up finding out you were pregnant? Did it result in any complications in your pregnancy? I would love to know your stories! I just got done with my period and before I started I tested negative on a hpt. I bled heavy for about a day a half then went to light then spotting. That’s about normal for me. But I feel tired all the time, peeing way more than usual and my boobs are still big! They normally shrink back down a day into my period. I doubt I am actually pregnant but of course it’s still in the back of my mind. I’m also just wondering what’s going on with me. Thank you in advance.
