1 positive preg test & the rest negative?!?!?!?

Cary

HELP! The last 2 months now I had 1 positive pregnancy test and the rest were negatives. Both months I ended up getting a period within 30-35 months cycles. 1 false positive would make me think the test was just wrong but 2 (1 each month???) could these have been chemical pregnancies? What could be going on? I just ovulated yesterday so we’re trying again, 5th month in a row now and I’m beginning to wonder what’s going on here? Any advice or has this happened to anyone else??
