In December, i started my period as usual, on the 14th. In january, i was due to start on the 11th, but didnt. I took some pregnancy tests early, that said negative and saw my doctor on the 15th, i was sure i was pregnant. on the 16th i took a pregnancy test at home at night, and it came back positive! the 17th in the morning i started my period. my doctor sent me for bloodwork but i didnt get it done until the 19th, and havent heard back yet about it. my husband and i decided to start trying to get pregnant, so we have done the deed almost everyday, or at least every other day, the last day we did, was the 31st. i usually am a 28 day cycle girl, and am usually regular, this is the first time i have been late in almost 3 years. in fact i was so regular it was our method of birth control. so i dont know if i could be pregnant, if i am, when would i have conceived, i was supposed to expect my period on the 11th, but it didnt actually come until the 17th, so would i have ovulated on the 31st, maybe before, or not yet? because i do want to be pregnant, but we didnt do the deed yesterday, so should we do it today?
