Way Past TWW

I'm new to this site and I' already so glad that I found it! Now I can share what I'm going through and see if there is anyone who could help. DH & I are TTC #2. I recently started first round of clomid (got pregnant w/DS on the 1st round 5 yrs ago) and I'm now on cycle day 39. My LMP was 3/25 and I think I ovulated on cd15 because I had a lot of pain in my right ovary. Then I had pain again on the same side after another week or so. Ever since cd15 I have had lots of lower abdominal cramping, severe bloating, low back pain, VERY sensitive nipples and I've been having to pee all the time. I'm a POAS nut and I've had nothing but BFNs. I even had a BETA done on cd 25 and that was negative. My last HPT was on Friday cd 39 and I got another BFN. I still don't have a period, have all the same symptoms and I don't know what is going on with me? Is it possible to still be pregnant even with a BFN on cd36?
