Help please

62 days since my last period and 4 negative hpt. I have been this late before but not while on clomid (Feb was my third month on it). I had a positive opk Feb 26 and 27th since I never ovulated before so I don't know if I did or didn't. (My PCOS issue is anovulatory cycles). Can I still be pregnant or is it false hope?? I have been really trying for 4 years but haven't prevented pregnancy in 10. I get lightheaded, my breast are heavier, I'm bloated, my hands are swollen, and I get out of breath easily. Has anybody here been in the same boat and it turned out that you were pregnant? Anyone please help. Can't get an appointment till may. Thank you in advance.
