Confused. Help? Mc

Okay so I had a miscarriage in November (20th) from which I bled heavily for around 2 weeks. All preg symptoms disappeared. Then I had my first menstrual cycle around Christmas. I have had sex three times since the miscarriage. One with condom and two with pull out. He didn't come inside me any of the times. And the pre cum also did not enter me as he pulled out way before this and I saw the pre cum. 
I'm assuming I'm ovulating now but have never actually had any symptoms when ovulating as my cycles are not really regular. I'm wondering if the miscarriage has caused me to have breast tenderness and slight cramping on one side of the abdomen? 
I don't think I'm pregnant again and even if I was I think it's too soon for any of these to show up as symptoms as it's less than two weeks since my last period. Is it normal to feel ovulation once if not having previously experienced it before? The miscarriage was hard but made me realise I am in no way ready to be a mother right now. The cramping is mainly one sided but often inborn since yesterday. I did get paranoid and start poking and feeling my boobs last night when I felt no pain apart from in one spot at the top of my right breast (this was the part which hurt the most before my mc). The other breast is not sore or tender. Or it wasn't until I started poking at it to see if it was sore. 
Sorry it's long. But what do you think? He definitely didn't cum or pre cum inside me.
