Begrudging my pregnancy

Im currently 10 weeks 3 days, and i feel so depressed. I feel i have to hide my pregnancy and not talk about it. I had an early mc in january at 5 weeks, and got pregnant again in march, i was ecstatic. My sister in law has had 3 eptopic pregnancies and has now had to have her tubes removed due to bad cysts, so cant have anymore children which devastated her. And i cried with guilt when i found out im pregnant again. I just found out my other sister in law had a mc at easter, she was due 2 weeks before me. When we told her we were pregnant (we didnt know about her at the time) she hasnt really spoken to us since and i feel really guilty now. Then yesterday, we were at my best friends daughters communion, and my best friends mother congratulated me and gave me a hug. Her dad said whats all this about and i joked saying have u not noticed im a little wider looking? My best friend then said real smart "no more than usual". I was a little shocked. She barely spoke to be for the rest of the day and i left the celebration early cos i felt so akward. I guess i just want to vent, i just feel like shit for being pregnant basically. My joy has turned into guilt and now i just want to hide away and not talk to anybody
