A few details, my wife gave birth to our beautiful daughter a few days shy of 10 weeks ago. She stopped bleeding 4 or 5 weeks later. After about a week and a half of no bleeding (at her 6 week checkup) she got back on birth control. A few days shy of two weeks on birth control, we had unprotected sex, once, and the next day, had protected sex. It had been a week and a half after the (no condom) sex and she spotted for a day. She had not had her first regular period yet, which is why we are confused as to what to expect for first period after giving birth. She took an EPT and was negative within the 3 minutes. However at about 7 min or so, a faint shadow appeared where the positive would be. Thick line, not thin. But you had to hold it up to the light in the right angle to see it. She took a First Response at the same time and was negative, no lines, not even after an hour. Any comments would help or similar situations. Shes too embarrassed to call the doctor at the moment. Additional Details She stopped breastfeeding at 2 weeks, not working out, out daughter wasn't getting enough and very gassy/colicky. It was a tough decision, but she is growing normal now on formula and is a lot less fussy.
