Miscarriage on March 25th

Hi y'all. Miscarriage started march 25th, So about 5 weeks ago levels were 2455. I bled for a week then it stopped. Levels were in the 100's about 8 days later. We've been having unprotected sex using the pull out method since one week after miscarriage. Not trying nor preventing. This last week my nipples are extremely sore. Had some lower back pain & very thick cm with minor ovary aches last Friday so I assumed I was ovulating but I seriously can't even touch my nipples without them hurting, also having really bad diarrhea the past 2 days. Still haven't had a AF since Feb 4th. Thoughts? I want to test - but I don't. Ya know?
