I have a dull feeling that comes and goes on my right side.

Around the middle of my cycle I started getting pinching on both sides at random times, and they were spread out and very mild feelings. I thought at first it was just my ovulation, because I was told it can cause some cramping, well that pinch would happen on and off, some days but not everyday. It was pretty random, but it happened leading up to when my period was due, so I was like hmm I guess period is coming? Or I have something wrong with body? Lol because I miscarried is December, and was doing my best to convince myself I wouldn’t be pregnant this month, because it’s to soon and I didn’t want to get my hopes up, when my period came. Well I googled and it said cramping that goes on a few weeks before a scheduled period can mean early pregnancy... I ignored that though, and thought maybe I had a cyst or something. Well my period never came and after my boobs have been so sore and thinking it was PMS, I took a test and it was positive. I keep feeling this dull ache on my right side though today.
