Advise please :(

I went on vacation November 6th-13th (Disneyland) I was supposed to start my period about the 7th and it came super late I finally got it the 15th, but the 13th I took a cheap HCG test and got a positive (I’ll add the photo) I’m not sure if it was a dud, an evap line, or what but I was so excited I went to bed and was gonna take another in the morning and then go to a clinic to confirm, we’ll took the test in the morning and it was negative and then I started the next day. My period was a bit longer than usual only by like a day. I have been taking LH tests since the 19th cd 5 since my period was so late I have no idea when I’m supposed to ovulate (attaching the photos of the LH tests) none of the LH tests looked positive to me... based on my apps they predicated ovulation around the 29th-3rd. I BD on the 30th and on the 1st.

What I’m getting around to is that I’ve been cramping for 2 days now, and today is especially crampy to the point it’s irritating, it’s in my pelvic area towards the more my right and shoots back to my lower back. Feels like full period cramps like what I experience on day one. Is it possible it’s period cramps and I’m gonna start? Or is it possible it’s implantation/pregnancy symptoms? This is our 7th cycle ttc. I’m too the point I literally cry thinking about babies or seeing them. I’ve been especially weepy lately. I just really need some advise. I feel super alone, I have no mom friends or friends that are in a stage where they are wanting to start a family and I don’t know who to talk to about what to do. Honestly really desperate. Thanks for helping me out.
