TTC 1 year

Trying to conceive for a year I have tried opk tests and got positive results but no pregnancy yet. I was 3 days late on my period last month and then came on heavier and longer than normal. Started tracking temp this month and had positive opk, pains had sex, next day had a temp spike now it's dipped again. My husband has been tested and no issues there. Any ideas what I can do next?
