Cry babyyyyy TMI a little bit

So like the past few days I’ve cried more the. My kids cry in a day!!!! I swear!!! Me and my ex broke up almost 2 months ago. We still see each other we have 2 kids together. We have had sex during this break up. I have not had sex with anyone else. Butttttty I had unprotected sex with him. He came inside me twice. Wasn’t expecting it at all. We talked about it just for like talk because it gets him turned on but he hasn’t done it since I got my birth control taken out earlier this year. So it was right after my period last month. Like a few day after but few days before ovulation. Last week I was ovulating and For a couple days at work I was cramping pretty bad it was annoying me and normally it doesn’t bother me but it did. And one night I went to bed and it was really bad I couldn’t go to sleep. I wanted to fry. Today I wiped and my discharge was pink, but only at the end of the stand of it. Like I barley noticed it, but it was pink. I took a test tonight and it was negative. I’m just curious if this could be implantation bleeding or spotting?? And maybe I tested to early? I’m not supposed to start my period for another week 1/2. Im laying down for bed and I’m cramping now too. It’s like all in my back and my front. 😐

I didn’t take a picture of the discharge earlier because my ex was here visiting with our kids and I left my phone in the other room and I thought it would be weird for me to go grab my phone then run back to the bathroom 😅
