Praying for a miracle! 4 days late, scared to test after major loss is May. Please help.

My SO and I conceived in our 3rd month trying in March and I was unbelievable thrilled! Imagine our horror and denial when they told me I had a blighted ovum at 8 weeks. We still held onto hope but finally went through with the D&C on May 6th at 11w1d. We took a break to let my body get back to normal and started TTC actively not this cycle but last. Well I'm 4 days late and I'm usually like clock work with perfect 28 day cycles. Only time I've been late in the last year was my BFP in March. Here's the craziest part...I was a moron and somehow left a tampon in or put a second one in while I had one already in and didn't realize it for almost two weeks and basically ovulated at the time I found it up against my cervix (so gross) and we were active the whole time! Until the day I found it there was no clue anything was wrong! Smh! So if I am pregnant this baby is truly meant to be. I'm scared to test though and scared to go through another loss but I'm experiencing rock hard boobs and they are absolutely killing me! Not the nipples the entire boob and they're big! I'm also have sharp stabbing pains on my left lower side in my ovary area. Please someone just help me work up the nerve to test! In March my period was due the 17th and I got positive on the 21st...If I'm pregnant I think it could show up if I test but I'm scared! AF was due the 21st and tomorrow would be the same amount of time. I just need some support. This month has to be the absolute craziest months! After I ovulated and found the tampon I got viral meningitis and had bronchitis on top of it and I'm just scared because of the meds I had to take. I feel so anxious. Please someone help me calm down!! Thank you my beautiful TTC friends! This is baby #1 and I've had Endo since I was 22 so seriously we're talking a miracle. My doctor said it was amazing I conceived the first time and we shouldn't have any issues again, but the last pregnancy with the blighted ovum was 2 chromosomal abnormalities which my doc assures me will not happen again....I'm not usually this scared but I'm a wreck. Thanks for listening. Xoxox Baby dust to each of you!
