Lesbian parents

Hi there ladies, my partner and I are TTC but through artificial insemination at home. I've read some success stories, and have been researching about getting pregnant. This will be my second child, but first through AI. I've only been trying for three months now with no luck. I was wondering if there was any other partners out there with my similar situation that might have some tips? I really thought we had it this month. Sore breasts, nausea, faint, all the signs pointed to pregnant, except the tests. Then I started bleeding last night and I cried. But I'm trying to stay positive. Just kinda feels like a lot of pressure. Any tips at all are more then welcome. Kinda feel alone in this. My partner is amazing. Staying positive, loving, caring. And is completely there for me. But I can't help but feel like a let down. Anyways, any advise helps. Good bless and thank you for reading.
