ugh i think im going mad

so after 2 chemicals i thought i would let myself have a full cycle avoiding pregnancy so i could work out the exact length it is after coming off the pill. itvwas 30days which was my normal from years ago that i can remember. going by that i am due to ovulate on sat so was going to do my clearblue ovulation tests from wed (usually get peak on cd16 which would be friday) today i totally feel like im ovulating,a heavy feeling in my womb. so do cheapy ov tests and think i got a positive one this evening but i find them really hard to read.cm is not stretchy,just lots of creamy. please tell me i havent missed our chance thks month.hate feeling like i have failed before we even had a chance this month...
