Is this real?

So I am a mom to a crazy 19 month old little lady and my husband and I had always planned for more. We didn't think that meant right now! It took us a year to conceive our little lady and also had a MC in there too. So we figured as long as we track my cycle do the opposite of what we did to get preggo the first time we should be golden right? WRONG! I got my BFP after testing randomly 3 times over the last week yesterday! It just doesn't feel real! I was super symptomatic the first go round and I legit feel nothing except some mild breast tenderness and bloating. I'm almost scared I'm going to have another MC just because I don't have any symptoms which I know is silly. Anybody else pleasantly caught off guard and still can't believe it?
