We've been trying to conceive for three cycles or so . Every month I have different symptoms sometimes I have frequent urination my last cycle I had pink spotting which I thought was implantation bleeding , I had morning  sickness a few days etc I tell my bf about it because I get excited but then I just get my cycle and negetive tests. In April I had a ultrasound she found a small cyst and my uterine lining was a bit thickened I supposed it was preparing for pregnancy she also said she saw a small uterine polyp . I'm frustrated because I'm trying to explain to him that I can't just keep making an obgyn ultrasound every cycle because I just "think" I'm pregnant . When my symptoms come and go and I have all negetive tests AND still getting my cycles that they will just laugh in my face. But he doesn't understand that it's very frustrating for me as well and people trying to conceive go thru this for months and even years until they get a positive . Today he got an attitude & told me he doesn't care anymore if it happens it happens if it doesn't it doesn't . This really hurts because I feel like he's just starting to not care about this at all . He is putting a lot of pressure and stress on me . Idk what to do. Advise please ?
