Could I be experiencing implantation??

Hey! So, today was predicted ovulation day but I believe I ovulated early this month around 4-5 days ago. I say this because 4-5 days ago I had a lot of Egcm when wiping and today I have nothing. I also had slight pain in my abdominal region around the same time but I don’t have anything today. Also, all opk tests were showing high but then I ran out of tests so I just decided I wasn’t buying anymore.

Anyway. We made love around 5 days ago, and then again the next night. We then made love last night also.

Since I believe ovulation took place, I have been experiencing breast tenderness, mild stomach cramping on and off, hot flushes (I couldn’t sleep the other night as i was just too hot) also, needing to pee more often than I did before.

I’m not going to test as it’s way too early but could this possibly be implantation occurring? I’ve had no blood. I had a mc in October last year and were now ttc our rainbow baby.

Please let me know what you think.
