Just need answers! Worried Momma 😔

So this last month in December we had a miscarriage and so everything went back to "normal" that month I ovulated at the end of the month very fertile too. January 10th I had my period but it was way different. It wasn't as heavy as normal and I spotted way longer than I normally do at the end of my period. Well January 24th I took a test because my boobs were just killing me for about a week or so and it came back positive (digital blue test) almost instantly. Just yesterday (1/30/17) I took another test and it didn't even take the full 3 minutes it came back positive after 30 seconds. For the past week or so I have been having brown spotting and the past 3-4 days there has been some dark red along with the brown. I've noticed it's more so in the morning after I wake up for the day and sometimes in the late evening if I've taken a nap. I guess I just want to know if this is normal or if this is alarming. Tonight I felt into the hole of my vagina and the tissue feels enlarged. Not sure what that could be either as with my 2 other pregnancies I never had any of these issues. Can someone help me please?? What do you all think? Thank you!!Â
