Scared and venting

So a little back story, I had a chemical back in October. I tested 4 days before my period was due and got a positive, MC within the next week or so. Tried again since. This time around I didn’t really track too much. Went to Gyno on Jan 29th for annual check up, she said I had ovulation mucus and to go home and do it lol so naturally we did. I didn’t really test for ovulation and not sure exactly when I would be due for my period but I knew it was at least two weeks ago since my appt. so I took a test last night and got a positive on first response, but a negative on clear blue digital. I had one pink spot last night, nothing since. I haven’t told my husband yet cause I’m just so nervous about another chemical. Why am I driving myself crazy?
