Dear Drs.

Im 28 I've never missed a period and I've been trying to conceive my regular cylce length is an average of 30 days. Usually the maximum the period could come late is 3 or 4 days my last period was on May 10th which makes me 17 days late I've done several home pregnancy tests and all came out negative. A week after the period date June 17th I've done a quantitative blood test and came out negative too then my dr priscribed me duphaston twice a day for a week and told me it would sustain pregnancy if there is one and at the same time would make my period come in 3-4 days after the last pill taken on June 23rd so I rested pregnancy blood test the following day amd came out negative AGAIN so my dr then told me lets wait until a time fram of 4 days after duphaston withdrawal and now it's the 4th day June 27th after withdrawal and still no period and still negative pregnancy results so today I'm on 48 days cycle and I donk know what do I'm wondering a I pregnant or not?! I also know that an ultrasound won't help at this stage it could figure out as well! So could I be pregnant but it could take more than 17days to see a positive? Please help me thanks a lot

Oh sorry forgot to add the symptoms I just had cramps at the time the period was due with some lower back pain still exist and a lot of discharges that I've never had before as well as a little pain at my lower left side of stomach as if there's something inside this part
