Can anyone help?

[ayahhh]

New here!
Would anyone be able to help?
I usually get ovulation cramps but the past 3 months I've not been getting them, AF was still showing up on time as my periods are always regular and I usually know when I'm starting as I start cramping the night before. But this month it has been different. I had some slippery CM (sorry TMI) and on the day of my period dry bar in the night when I noticed I had some brown rusty blood. This isn't unusual as my period does start like this, however it stopped and nothing during the next day and night on the 3rd day I got a little pinkish blood again only a small amount (used a panty liner) and again nothing for the rest of the night.. today again I'm back with the brownish blood. I've been having slight cramps like my period is coming but not as bad. I've tested and it's negative. We have been TTC'ing for 3 months but not as well as we would like due to work and moving homes.

Has anyone else had this? I've done 3 test and all 3 are negative.. oh and also just before the OV pains stopped I felt sharp pains on both sides and no more OV pains anymore.

Has anyone else had this? Could I be pregnant or is it something else?
