Has this happened to anyone who had a bfp before?

So I have been trying to concieve for 3 months. My period is usually regular , could be off by no more than 4 days . I have been tracking it for about a year and it’s never been more than 4 day difference for instance , if my period was on CD 13 , last month , the next month it can come between CD 13-CD17 . Well according to my calendar in the month of March I got my period on CD 27 and ovulated the 13th. Then in April I got it on CD 31 and ovulated the 17. , and then may I got it on CD 18 and it says I ovulated on CD 4. It came extremely early only abt 2 weeks after my period already ended . So basically the app is saying I ovulated during the last days of my period . The prediction for this month says I’m going to ovulate on cycle day 11 which is May 17. I have taken OPKs but I was using the clear blue one and it was a flashing smiley so it detected something that meant I was going to ovulate soon and that was all the way on May 14. But my cm was kind of creamy then , since May 22 I have had very very watery cm. I check my CM everyday and I haven’t seeen the EWCM but its been extremely watery and I’m having AF type cramps. Like a heavy feeling in my abdomen area , and it just feels like AF will be here any moment . I’m not sure when I ovulated though , I took a test but it was negative. I keep going to check because it just feels like AF is coming . It’s so watery and milky white . Everytime I have sex I have used pre seed also. I will also post my app so u can see the cycle days and when I had sex. Has anyone see a BFP after very watery CM? Has anything like this ever happened to anyone ?

Note- I had sex more times in March than it shows , I didn’t log it though. Also my cervix was very high since the 14th of May and seemed also squishy. It still seems high now . But it feels more firm yet still high .
