Opinions?

hi ladies. I'm super new to the forums. any who. Down to the questions and opinions. Husband and I have been trying for #3. I went off the pill 03/17. It threw off my AF for 1 month. after that I had a normal 28 day cycle. after about 3 months it went to 31 days. then that became normal. Last 2 Months it went to about 36 days. I can not tell you how many home test I've done in those times I was late. I'm not late now. My last period started July 9 lasted 6 days usually only 5. The 27th of this month I had a creamy white lotion like CM with pink blood mixed. Now I'm having off and on cramps. Not like my other pregnancies. it's like emergency bathroom type cramping. only I can't go. I have no Idea when I really ovulated or if I did honestly. do you think the 27th was just ovulation? or could have ovulated normally just long cycles? it's driving me insane... what are your opinions?
