Looking for thoughts

first time mom

So I took an ovulation tests on the 26th and 27th of Jan both positive. 25th test was negative. Of course my partner and I have had sex every day to every two days the whole month. I’m thinking I ovulated either 28th or 29th. Today I started to spot. Very extremely light (more pink then reddish) when very light cramps. I typically have horrid cramps on my period. This feels different but don’t want to get my hopes up. I started crying as soon as I wiped and saw the blood. We have been trying for awhile now.. do you think it’s start to a period, implantation cramps? My last period was Jan 14-16 (3 days). I ovulated very late into my cycle about 16 or 17th into it. This spotting is now day 28th of the cycle. My cycle is averaging 26 day besides this one. Took pregnancy test 3 days ago negative.

Just looking for thoughts or experiences.

Thank you!
