I've barely had periods for over 6 years. Went on tablets to induce periods and had 1 cycle. Ever since I've had periods on my own (3) my ovulations tests have been faint but there. My last period was barely anything and last a few days, I was supposed to be ovulating yesterday but did a random pregnancy test today which has a faint second line. But 2 other didn't. I'm so confused. It's not out of date (surprisingly it's the cheaper one positive and clear blue negative) my next periods not due for 15 days. Any advice ?
