No missed period but 2 positive pregnancy tests?!

My husband have been ttc for 3 months. I got my period as usual last month, although it came and went for a few days. I thought nothing of it. Now it is time for me to be ovulating. I took 3 opt 3 days in a row and they all showed a LH surge, so today I took 2 pregnancy tests and both were postive. I don't feel pregnant, but I am so worried after getting my period I drank.
